Watlow POWER SERIES Controllers
Microprocessor-Based SCR Power Controller Designed for Application Flexibility
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.

Fire Shield Cords
Sords Electric Sell Fire Shield Cords and strips.
Fire Shield is the safest cord on the market.
Fire Shield products are ideal for home, office, and campus environments such as residence halls, labs, classrooms, libraries and other facilities. Fire Shield cords, with specially designed shielded conductors, are able to detect series faults and line-to-neutral faults, significantly reducing fire hazards. Available as power strips, surge protectors, appliance cords and extension cords.
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.
Cords with 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.
Causes of cord fires are unintentional misuse of extension cords. 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.
Fire Shield 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. Please check our website to find the Fire Shield Surge Protector best suited for your requirements.
Many colleges and Universities now require that only the fire Shield cord and strips be used in dorm rooms. Cord fires are the leading cause of fire in dorm rooms. Please review the "Can you Prevent Univertiy Dorm Room Fires" brochure.
Fire Shield products are UL and CSA approved and can be purchased at www.sordselectric.com.

Sords Electric sells Watlow Power Controls. A power Control is a large switch, meaning in possible amperage capacity and even in physical size. An SCR power control can switch voltage up to single cycle of the AC voltage sine wave.
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.
