Standard Features and Accessories150 kW Power Supply with doors open

  • Designed and constructed for easy operation and low maintenance

  • High electrical efficiency

  • Single electronic Logic Control Board inisolated (door-in-door) enclosure

  • Cabinet is constructed from rugged heavy 10 gauge steel

  • All components are readily accessible through a large front door and side door for easy service and maintenance

  • Cabinet can be flush mounted against a wall, no rear access is required

  • 3 Phase, SCR controlled Electric DC Circuit Interrupter shuts the power off in the event of an inverter or furnace failure. This prevents the loss of expensive fuses, damage to the circuit breaker and protects inverter components.

  • Diagnostic Circuit Monitor displays where to locate faulty components and indicates electronic limits

Optional Features and Accessories

  • Cabinet is set up for the addition of up to three furnace switches for alternate operation of multiple furnaces.

  • An internal closed loop water system to protect all power supply components from dirt and electrolysis. The system, which is built into the power supply, cools all internal components with low conductivity distilled water. A required external water cooling source cools the internal system plate type heat exchanger and furnace(s).

  • Cabinet can be manufactured “Left Hand” as pictured above or “Right Hand” (mirror image).

  • Electrical Ground and Molten Metal Leak Detector for continuous monitoring and detection of molten metal penetrating the induction coil, excessive moisture being present in the furnace lining, and low ground resistence in the isolation transformer. If the unit detects any of these possible occurrences, operator is immediatley notified. Programmable Logic Touch Screen Controls

  • Remote Control Panel for remote operation of the power supply.The Remote Control Panel can include an optional Circuit Monitor Assembly.

  • Logic can be interfaced with Programmable Logic Control (PLC) "touch screen" controls (shown right)

  • Meter Panel Assembly can be supplied with either analog meters (shown right) or digital meters (shown below)

POwer Supply TestingWhy choose ITC ?

ITC strives to provide high quality equipment at competitive prices. To ensure that we ship only high quality equipment to our customers, all power supplies undergo complete function and electrical testing under power. During the testing process, all safety and interlocks are tested and set, and when possible, the customer’s furnace load is simulated for optimum performance.


Important Note About Cooling Water

Controlling water quality is the “Secret” to trouble free operation and long life of induction equipment. Severe damage from electrolysis, scaling, blockage and overheating can result from poor water quality. The best way to prevent these problems is with a Closed Loop Water Cooling and Recirculation System where water conductivity and cleanliness can be maintained. ITC can offer the correct cooling system based on your geographical location and specific usage. The proper cooling system will extend the life of the equipment, reduce down time and maintenance costs.
