Watlow EZ-Zone ST Temperature Controls

The EZ-ZONE® ST integrated solid state controller
from Watlow® offers a complete thermal system control solution in a single package. Features include a PID temperature controller connected to a high-amperage solid state relay with the option of adding a properly sized heat sink, an over- and  under-temperature limit, a power shut-down contactor and digital communications in one complete and professionally engineered product.

Because the solid state controller system is modular and scalable, a user only pays for what is needed. Stacking the EZ-ZONE ST integrated controller into multiple configurations enables flexibility to standardize the product platform to solve a wide range of application needs.  More information can be found in the EZ-Zone ST section at Watlow.com.

Watlow DIN-A-MITE D Power Controls

The DIN-A-MITE Style D is capable of zero-cross switching up to 100 amperes single-phase, at 600VAC at 86°F (30°C), depending on the model selected. Two or three controllers used together can control three-phase. It is totally touch-safe and includes standard back panel mounting, on-board semiconductor fuses (accessible from the front) and a current transformer option for external load current monitoring. An optional “shorted SCR detector” feature is available on some models. This model is UL®508 listed and C-UL®and CE certified. These agency approvals are ideal for those panel builders that require agency approvals on their panels and cabinets.

Variable time base, 4-20mA process control, or VAC/VDC input contactor options are available. All configurations are model number dependent and factory selectable. This power controller also includes 200KA short circuit current rating (SCCR) tested up to 480VAC to prevent arch flash with required fusing.

Watlow Power Series Power Controls
Watlow Power Series Power Control

Watlow's POWER SERIES solid state controllers include single- and three-phase models from 65 to 250 amperes. Field configurable phase-angle or zero-cross firing improves application flexibility on-site where needed.

50/60Hz independent operation allows utilization almost everywhere in the world without special calibration considerations. Serial communication via Modbus® RTU allows setup and monitoring of load status from a 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 these benefits are in a touch-safe package that can be quickly and easily mounted in a control cabinet. Watlow's POWER SERIES solid state controllers are UL® listed and C-UL® recognized, ensuring that they meet world safety and operational standards.

Watlow QPAC Power Control

The QPAC modular controller from Watlow is a modular silicon controlled rectifier (SCR) power controller with plug-in features for flexibility. Bases are rated from 150 to 1000 amperes in one-phase, three-phase, two leg and three-phase, three leg configurations.

A variety of transformers from 120 to 575VAC, along with 50/60Hz operation, enable the QPAC modular controller to operate in applications anywhere. Plug-in control cards set the QPAC's SCR firing modes: solid state contactor, burst firing (zero cross) or phase-angle models and are available with a wide variety of options. High speed fuses are included to protect the SCR modular controller from short circuit currents. 200KA short circuit current rating (SCCR) prevents arc flash.

Watlow E-SAFE II Power Control

The E-SAFE® II hybrid power switch provides reliable and accurate power switching up to 35 amperes at 158°F (70°C). This mercury-free product is specifically designed to operate in the higher ambient temperatures of foodservice applications. Because of the product's unique design, there is no need to purchase costly heat sinks used with traditional solid state relays (SSRs). In addition, since this is a three-phase device, there is no need to wire multiple command signals. With a switching life of millions of cycles and an ambient rating of 158°F (70°C), with no heat sink required, this product is superior to typical SSRs.

By using Watlow's patent NO-ARC technology, the E-SAFE II can switch millions of cycles to increase the life of the product with reduced noise and increased temperature accuracy. E-SAFE II's inherent ability to operate at fast cycle times make it an ideal complimentary product for a time, proportional, integral derivative (PID)controller.
