Watlow Power Controls

Anderson-Bolds sells Watlow Power Controls.

Watlow solid state power controllers complement the rapid switching required by PID temperature controls and help deliver optimum system performance and service life. Available in 1-phase and 3-phase/2-leg and 3-leg configuration, Watlow power controllers meet most industrial heating applications. Random, zero cross or phase angle fire options allow for a variety of applications.

DIN-A-MITE^® SCR

The DIN-A-MITE family is the ideal solid state replacement for mercury displacement relays (MDRs) in an easy-to-install, compact, touch-safe package. The solid state power controllers provides SCR control, heatsink, wiring and touch-safe exterior in one package. By designing the DIN-A-MITE as a total power controller unit, the need to prep wires for terminals, locate the right heatsink and determine adequate terminations is eliminated. It's a complete package you can install easily with CONTROL CONFIDENCE^®.

Four DIN-A-MITE styles meet most power controller needs with ratings from 18 to 100 amps with voltages from 24 to 600V~(ac). The four models match load requirements with 1-phase, 3-phase/2-leg and 3-phase/3-leg switching. The controllers also provide a convenient DIN-rail and sub-panel mount package.

DIN-A-MITE A	Up to 25 amps	Single-Phase	Contactor or Burst Fire
DIN-A-MITE B	Up to 40 amps	Single- & Three-Phase	Contactor or Burst Fire
DIN-A-MITE C	Up to 80 amps	Single- & Three-Phase	Contactor, Bust, Phase
DIN-A-MITE D	Up to 100 amps	Single-Phase	Contactor or Burst Fire

POWER SERIES Microprocessor-based SCR

• Ratings from 65 to 250 amperes
• Offers extensive system and heater diagnostics features and agency approvals

For over thirty years Watlow^® has been manufacturing solid state power controllers. Watlow's new POWER SERIES represents the latest in SCR power controller technology. This microprocessor-based product offers features and application flexibility unmatched by any other SCR power controller on the market today.

Capabilities include single-phase and three-phase models from 65 to 250 amps. Field configurable phase angle or zero-cross firing improves application flexibility on site where you need it. 50/60Hz independent operation means you can operate almost everywhere in the world without special calibration considerations. Serial communications utilizing Modbus^® protocol allow for remote control setup, and monitoring of load status from a nearby computer station or control room.

On-board semiconductor fusing improves reliability by protecting the SCRs from heater short circuits. Plus, on-board heater bakeout and control diagnostics can help eliminate initial start up problems. All this in a touch-safe package that can be quickly and easily mounted in your control cabinet.

SERIES CZR

• CSA, VDE and UL® recognized contactor
• Ratings from 18 to 50 amperes single phase
• Single solid state relays from 10 to 75 amperes

The new SERIES CZR solid state contactor from Watlow^®provides a low-cost, highly compact and versatile solid state option for controlling electric heat. With DIN-rail and back panel mounting standard on every controllers, the CZR allows for simple and quick installation.

The extensive capabilities of the SERIES CZR include single-phase, 24 to 50 amp zero-cross and random switching up to 600V~ (see output rating curve). The unique integrated design removes the guesswork associated with selecting a proper heat sink and precise terminations for the application.

This controller holds many agency approvals and is ideal for applications that require UL^®, CSA and CE approvals. SERIES CZR contactors are available inV (ac/dc) input contactor versions. All configurations are model number dependent and factory selectable.

The SERIES CZR is reliably backed by a two-year warranty from Watlow.
