Input AC up to 300VAC,  DC out up to 300VDC, 20A @ 110VDC.

Kits in 500W, 1kW, 1.5kW, 2kW, 2.5kW  continuous, 3.5kW peak for 2 minutes.

30kHz, H-bridge IGBT (or MOSFET if requested) current mode PWM control, slope compensated, soft start, current limited and volt limited on o/p.  Input over volts protected, UVLO and over-temp shut down.

Input inrush limit at plug in, RFI filtered at AC in (& snubbers on IGBT's and diodes), low leakage main transformer, optimised gate drive to reduce RFI.

4 x diode bridge rectifier output, 10% current ripple in o/p choke typical.

Supplied fully working on heatsink bracket, app notes and design notes supplied.

Power factor ~ 0.7

Auxilliary flyback supply on board (TNY268), supplying 2 x 15V out and +/- 15V, all isolated, and one primary side 15V supply.  15 watts total draw.

Get the kit, change the transformer and see the effect - change the snubbing and/or the gate drive to see the effect on RFI, change the operating frequency (15kHz to 50kHz)  to see the effect on transformer core heating and winding heating for the same o/p power.  Change the power transistors and or the o/p diodes to see the effect.

Components easily probed to see whats happening on the 'scope, current transformer output also easily viewable.

Make changes to the control pcb (UC3856) and observe effect on power board.
