Brand new Switching power supply, open frame, made by Lambda
Still in original OEM box.

+ 45 Volt @ 2 Amp, continuous
- 45 Volt @ 2 Amp, continuous

Can deliver 3A peak for audio transients.

also 5V and 3V outputs @ 3 A, good as housekeeping voltages for lamps, relays etc.

Trimpot adjustable voltages from 43 - 50 V.

Voltages can also be lowered to as low as +/- 38V if needed, with a simple modification ( 2 parts) to the feedback loop.
This way it can also be used to power chip amps.

Instructions for use included. On request, full instructions and parts (1 resistor, 1 zener diode) for lower voltage modding can be provided at 50 cents extra.

Low EMI, short-circuit protected.

Size: 4 x 7 x 1.75 inches.
Excellent replacement for large, heavy power transformers, makes possible slim, sleek, lo profile power amp design.

Total continuous output power: 200W. multiple units can be connected in series/parallel for greater currents or voltages.

Price : $20.00 US, will ship to NA for $4, Europe for $6.
