Coax Valves for Flow Control

Coax Valves from Anderson-Bolds

For over 45 years, the coaxial valves developed by our company have formed a tried and tested element in the control of vacuums and gaseous, liquid, gelatinous, abrasive, contaminated, and aggressive media.

The coaxial valve design allows - as compared to conventional valves - high pressure media to be controlled at high flow rates. Our coaxial valves are available in 2/2 way or 3/2 way versions with threaded or flanged connections. The valves are actuated either by direct-acting solenoid or externally controlled.

TECHNICAL DATA

SSAC Products

Timer-DOM 100-240VAC/DC 1A DIPsw 1-1023s 2x2

The TDU and KSDU Series are encapsulated solid- state, delay-on-make timers that combine digital timing circuitry with universal voltage operation. The TDU offers DIP switch adjustment allowing accurate selection of the time delay over the full time delay range. The KSDU is factory fixed from 0.1s to 10,230s and does not include the DIP switch. These series are excellent choices for process control systems and OEM equipment

3Ph Voltage Monitor 200-480VAC Adj 8 pin

The PLMU Series continuously measures the voltage of each of the three phases to provide protection for 3-phase motors and sensitive loads. Its microcontroller senses under and overvoltage, voltage unbalance, phase loss, and phase reversal. Protection is provided even when regenerated voltages are present. Universal voltage operation and standard base connection allows the PLMU to replace hundreds of competitive part numbers.

Liquid Level-Drain Dual 120VAC Relay Adj 8Pin

The LLC5 provides dual probe conductive liquid level control in a convenient octal plug-in package. Models are available for fixed fill or drain operation. Isolated, pulsed DC voltage on the probes prevents electrolytic plating. Less than 1 mA of current is used to sense the presence of conductive liquid between the probes and common. On adjustable units, the sensitivity adjustment eliminates false tripping caused by floating debris and foaming agents.

Flasher 120VAC 1A 75 fpm 6 inch wires

The FS100 Series (low amp) may be used to control inductive, incandescent or resistive loads. This series offers a 1A (fullwave) or a 2A (halfwave) steady state, 10A inrush solid-state output and may be ordered with an input voltage of 24 or 120VAC. The FS100 Series offers a factory fixed flash rate of 75 FPM or may be ordered with a fixed, custom flash rate ranging from 45 to 150 FPM.

Fire Shield for College Students ~ PROTECTION from Dorm fires

Fire Shield is a next generation extension cord with built-in intelligence to sense cord damage and shut off the power before a fire can start. No other extension cord has this capability.

Industry statistics indicate there is a cord fire approximately every 6 minutes. The most frequent causes of such fires are short circuits, overloading, damage, and/or misuse of extension cords.

A special shield surrounds each of the insulated conductors of the Fire Shield Extension Cord. The shield is continuously monitored by electronics in the plug head. When a dangerous electrical condition is detected by current leaking to the shield, power is shut off before a fire can start.

Fire Shield differ from GFCI's and ground conductors. Grounded conductors only provide a path to ground. GFCI’s detect ground faults. Neither detects the breakdown in the insulation of a standard extension cord, which can lead to an arcing condition that may start a fire. By utilizing a sensing shield around the insulated Fire Shield conductors combined with intelligent electronics in the plug head, Fire Shield can detect damage in the cord such as series faults (broken and frayed conductors) and parallel faults (insulation damage between the live conductors), and shut off the power before a fire can start.

Unintentional misuse of extension cords is the main reason for cord fires. Cords may be crimped, pinched, frayed, overloaded, overheated, or just worn out. Any of these conditions can lead to an extension cord fire. Fire Shield can detect any leakage currents from these conditions and shut off power before a fire can occur.

The cord fire protection is a function of the special shield and relates to the Fire Shield extension cord only.

Fire Shiled should be used anywhere you use standard extension cords or power strips; in children’s rooms, pet areas, with space heaters, electric blankets, waterbeds, etc. Children and pets have been known to bite or chew electrical cords. Fire Shield, with its built-in intelligence may provide protection in these circumstances. Fire Shield Safety Extension Cords should also be used during the holidays with Christmas trees and other holiday decorations because of the tendency to overload extension cords.

Standard surge protectors only provide protection against power surges, which is important. However, standard surge protectors do not provide cord fire prevention. TRC has recently introduced a next generation line of Fire Shield Surge Protectors that not only protects against power surges, but also provides cord fire prevention.

Fire Shield cords are now required at many colleges as the only power strip allowed in college dorms. This is due to students overloading the strips, or tacking the cords to walls or pinching the cords between doors or around corners. All these issues can and will cause fires.

Fire Shield cords are patented and UL/CSA approved.

SSAC Timers-Voltage Monitors

SSAC timers and voltage Monitors:

These are three of SSAC's more common items:

The SSAC TRDU Series is a versatile universal time delay relay with 21 selectable single and dual functions. The dual functions replace up to three timers required to accomplish the same function. Both the function and the timing range are selectable with switches located on the face of the unit. Two LED's indicate input voltage and output status. This device offers full 10 A isolated relay output contacts in either SPDT or DPDT. The TRDU replaces hundreds of part numbers, thereby, reducing your stock inventory requirements.

The SSAC PLM Series continuously measures the voltage of each of the three phases. It separately senses Undervoltage, Voltage Unbalance (including Phase Loss), and Phase Reversal. Protection is assured during periods of large average voltage fluctuations, or when regenerated voltages are present. Both Delta and Wye systems can be monitored; no connection to neutral is required. 380 V AC and 480 V AC units are encapsulated.

Operation

The output relay is energized and the LED glows when all voltages are acceptable and the phase sequence is correct. Under and unbalanced voltages (including phase loss) must be sensed for a continuous trip delay period before the relay and the LED are de-energized. Re-energization is automatic upon correction of the fault condition. The output relay will not energize if a fault condition is sensed as power is applied.

The SSAC TDR Series of time delay relays are comprised of digital circuitry and a separate oscillator to provide high accuracy and stability. The ON and OFF delays are selected by means of ten binary switches, which allow the setting of the desired delay the first time and every time. Full 10 A isolated DPDT output contacts.

Operation

Upon application of input voltage, the output relay is energized and the ON time begins. At the end of the ON time, the output de-energizes and the OFF time begins. At the end of the OFF time, the output relay is energized and the cycle repeats as long as input voltage is applied. The OFF time may be the first delay in recycling timers. Reset: Removing input voltage resets the output and time delays, and returns the sequence to the first delay.

Overview
SSAC designs and manufactures electronic controls for original equipment manufacturers: commercial appliances, heating, ventilating, air conditioning and refrigeration equipment, vending equipment, pumping equipment, elevators, etc.; for process control and automation designers; obstruction lighting control designers; and for a large group of industrial customers and service contractors. Sales representatives and stocking distributors are located throughout the world.

An ISO 9001 Company (view ISO certificate)
For more than 30 years, SSAC has achieved new levels of product, quality, and service. Our customers demand quality and they get it. SSAC was the first North American Timers and Controls Company to have an ISO 9001 Registered quality system in place. Our ISO 9001 Quality Management System monitors all aspects of the business process: from the design process to purchasing, incoming material to shipment and customer service. At SSAC we design quality into our products. All of our processes are documented for sustainability and customer satisfaction. Our goal is to make every customer completely satisfied with the best products and services through continuous improvement and employee involvement.
