CARLO GAVAZZI has launched the new CD34 Series liquid level capacitive sensors. The CD34 Series is designed to detect water-based liquids through non-metallic walls, i.e. plastic or glass. The sensors automatically account for the thickness of plastic or glass walls and compensate for any residual films, moisture or foam accumulation while reliably sensing the presence of the liquid to be detected. The sensor is packed with a universal bracket, which provides great mounting versatility for a variety of surfaces, circular (e.g. sight glass, round containers) or flat.

CARLO GAVAZZI has unveiled two new single phase AC DIN-rail switch mode power supply families, in housings that are among the most compact available. These new additions to Carlo Gavazzi’s extensive lineup of power supplies include features and price points that are well-suited to a wide variety of markets and applications. The SPDM Series is a general purpose family with industry standard features in the most common output configurations. These smartly priced models are available in ranges from 30W up to 240W, in 12V and 24V outputs, and in housings that are up to 30% smaller than similar types on the market. The SPDC Series offers the highest level of features and performance, in slim metal housings. They feature efficiency levels above 90%, built-in Power Factor Correction, and can provide 150% power boost for up to 3 seconds, making them ideal for applications with high inrush currents. With built-in parallel function and an output ready relay, the SPDC Series helps ensure power is always available for critical functions. These advanced models are available in 120W, 240W, and 480W output versions.

CARLO GAVAZZI unveiled the new DUB72 Series, a double under voltage monitoring relay that is approved for use in Class I Division 2 hazardous locations. This relay can be used to help prevent brownouts in 24 VDC supplied systems in any kind of application, including hazardous environments. The DUB72 features two independent set levels and outputs, which allow the use of one as a pre-alarm and the second one as an alarm. With a high powered electromechanical 20 amp relay, the second threshold / relay can be used to directly disconnect a battery or load. Its low-profile DIN housing can fit into electrical distribution panels as well as into industrial cabinets.

SSAC/Littelfuse Voltage Monitor HLMUDLAAA

Voltage Monitor Protection Relay HLMUDLAAA from Anderson-Bolds
Made by Littelfuse

Contact Anderson-Bolds

LittelFuse SSAC Voltage Monitor HLMUDLAAA is a universal voltage monitor. 10 amp output relay rating. The HLM Voltage Monitor senses over or under voltage AND phase unbalance and frequency fluctuations and trips if any go oout of range. The Voltage Monitors are currently made by Little Fuse. UL, CSA and CE. Previous manufacturers were SSAC, Entrelac, ABB and Sycom.

The HLMU Series is a universal voltage, encapsulated, 3-phase voltage monitor. It continuously measures the voltage of each of the three phases with microcontroller accuracy and compares the value to preset trip points. It separately senses phase reversal and loss; over, under and unbalanced voltages; and
over or under frequency. Protection is assured during periods of large average voltage fluctuations, or when regenerated voltages are present. The unit trips within 200ms when phase loss is detected. Adjustable time delays are included to prevent nuisance tripping and short cycling of sensitive equipment. The isolated, 10A, DPDT relay contacts trip when a phase voltage exceeds the trip limits for the trip delay. Nominal line voltage, voltage unbalance, and time delays are knob adjustable. The phase loss setpoint and the acceptable frequency range are fixed. Both delta and wye systems can be monitored; no connection to neutral is required.

Voltage Monitor HLMUDLAAA

BENEFITS

Constant monitoring to protect against phase loss, phase reversal; over, under, and unbalanced voltage; over and under frequency
Flexibility to work in 200 to 480VAC applications
Installation flexibility
Provides diagnostics of relay, fault and time delay status
Protects against shock, vibration, and humidity Meets IEC 61000 safety requirements

Operation

Upon application of line voltage, the output is de-energized
and the restart delay begins. If all the three-phase voltages are within the acceptable range, the output energizes at the end

of the restart delay. The microcontroller circuitry automatically senses the voltage range, and selects the correct operating frequency (50 or 60Hz). The over and under voltage trip points are set at ± 10% of the adjusted line voltage. When the measured value of any phase voltage exceeds the acceptable range limits (lower or upper) the trip delay begins. At the end of the trip delay the output relay de-energizes. If the phase voltage returns to an acceptable value before the trip delay expires, the trip delay is reset and the output remains energized. Under, over, and unbalanced voltages plus over or under frequency must be sensed for the complete trip delay before the unit trips. The unit trips in 200ms when phase loss or reversal are sensed. The unit will not energize if a fault is sensed as the line voltage is applied. 

Reset: Reset is automatic upon correction of the voltage or frequency fault or phase sequence.

Restart Delay Options
L = Lockout or minimum OFF time. The restart delay begins when the output trips. The unit cannot be re-energized until the restart delay is complete. This provides a minimum off time

or lockout time to allow equipment sensitive to short cycling, time to reset. If the fault is corrected after the restart delay is complete, the output energizes immediately. The restart delay also occurs when line voltage is applied/reapplied.

R = Restart Delay on fault correction. The restart delay begins when line voltage is reapplied or when a voltage fault is corrected. This option is normally selected when staggered restarting of multiple motors on a power system is required.
N = No Restart Delay. 0.6 second initialization delay on application of line voltage applies.
Restart Notes: All restart options remain reset when the following conditions are detected:
1. Phase loss (phase unbalance greater than 25%) 2. Average line voltage less than 120VAC
3. Phase reversal

The restart delay begins when the condition is corrected.

LED Operation
The LED flashes green during the restart delay, then glows green when the output energizes. It flashes red during the trip delay then glows red when the output de-energizes. It flashes red/green if phase reversal is sensed. If a fault is sensed during the restart delay, the LED will glow red during that portion or the full restart delay.
