Statipower® SP18 Transistorized Induction Power Supply

The Statipower^® SP18 power supply is a solid state water-cooled system designed for case hardening, through hardening, annealing, mass heating, and many other applications. Power and frequency combinations from 150 to 600 k W/3 to 50 kHz are available in single and dual frequency models.

Transistorized Circuitry For Improved Reliability

All Statipower^® SP18 power supply systems incorporate “Try-Again” circuitry to eliminate nuisance shutdowns caused by voltage transients, ground faults and shorted or arcing loads. Because load current is not used for commutation, equipment can be operated with the output shorted for easy troubleshooting. Solid state accuracy assures output power regulation of ±1% with a line variance of up to ±10%. Reliability is further enhanced by placement of 95% of all circuitry on one control board which is accessible without entering the high voltage section of the power supply.

Reliable Design For Safety And Long-Life Performance

Statipower^® SP18 power supply units have a DC diode bridge, line choke and capacitor bank to minimize the effects of line noise and harmonic feedback. This also ensures a constant input power factor of 0.95 regardless of loading resulting in lower electric demand charges. All power components with DC potential are electrically insulated from the water cooling circuits. This eliminates the possibility of electrolysis. Other system features include an input line disconnect with UVR, output isolation transformer, differential pressure switch and temperature switches on water supply and return manifolds.
