Power Supply For General Purpose Induction Heating |
|
| |
The UNIPOWER® UP16 is a self-contained, solid state transistorized power supply 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. |

|
Unitized Design For Stand-Alone Operation |
|
| |
| Simply 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. |
| |
|
Remote or Computer Controlled Operation |
|
| |
| Remote control can be accomplished by connection to the user interface provided. Heat level can be controlled by a remote potentiometer or 0-10 V analog signal from a PLC. Options include a 4-20 mA process control signal or RS-232/485 interface for remote computer monitoring, data logging and control. |
