* Pulse power supply
This unit has a built-in power regulator which
converts the power supplied by the 12 V DC car
battery into high speed pulses using a semiconductor
switch. These pulses are stepped up by the built-in
pulse transformer and separated into both positive
and negative power supplies before being converted
into direct current again. This is to regulate
fluctuating voltage from the car battery. This light-
weight power supply system provides a highly
efficient power supply with a low impedance output.
