Power Supply For General Purpose Induction Heating. |
|
| |
The UNIPOWER Tm UP1 2 is a self-contained system for hardening, tempering, bonding, coating, brazing and many other induction heating applications. A wide variety of single-turn and other low impedance heating coils can be properly matched with built-in load tuning capacitors and multi-tap output isolation transformer. An optional external tap switch allows the operator to safely and easily change the transformer ratio without tools. |

|
Unitized Design For Stand-Alone Operation. |
|
| |
Just connect three phase 415 v input power, cooling water and heating coil and you're ready to begin heating. The cabinets are designed to accommodate a variety of fixtures, conveyors and part handling machines. complete stand-alone control and monitoring include: Manual start/stop push buttons, heat level control with 10 turn lockable dial, four meters and annunciator lights to monitor all operating parameters. A digital timer is also included to precisely control the heating cycle. |
| |
|
Remote Or Computer Controlled Operation. |
|
| |
Remote control from simple to complex can be accomplished by connection to the user interface provided. Heat time can be controlled from a simple foot switch, machine control relay or in a complex system by the process line PLC. Heat level can be controlled by a simple remote potentiometer, an optional 4-20 mA process control signal or with an analog 0-10 V signal from a PLC. An optional RS-232 interface is available for remote computer monitoring, data logging and control. |
