Gives continuously variable a.c. and d.c. output upto 10A for a.c. and 8A for d.c. A meter is provided to indicate both a.c. and d.c. voltages. An internal fuse is provided for input and a resettable cut-out for output. With detachable 1.5 meter mains lead.

Specifications

Mains Input : 220-240V 50/60 Hz

Output Voltages : 0 to 25V a.c. and under smoothened full wave rectified d.c.

Output Current : 10A maximum a.c., 8A maximum d.c.

Voltage Selection : Rotary continuously variable transformer operated

by a large knob on front panel.

Metering : A.C. and D.C. output voltages by a moving coil

meter with selector switch to select a.c. or d.c.

These power supplies are D.C. regulated, stabilized, short circuit and overload protected, easy and safe to use as a power source for electronic equipment.

The power supply can be operated in either constant voltage on constant current mode. Both voltage and current and precisely regulated with low output ripple. Voltage and current readings are displayed on two separate 3½ digit meters.

Output voltage, single or double, is continuously adjustable from 0 to 30vots by coarse and fine controls.

Specifications

Mains Input : 3½ digit panel meters separately for voltage and

current.

Accuracy of DPM : ±0.2% of readings, ±2 least count

Regulation : ±0.05 for current, ±0.05 for voltage

Ripple : Less than 3mv, r.m.s.

Input Voltage : 230 Volts ± 10%, 50Hz

Capacity : 1 Amp 2 Amp 5 Amp

These are built in nicely finished steel, cabinets having lock type terminals, On/Off switch, and jewel light. Full wave bridge rectifiers, double wound transformers are used with copper wire and high-grade laminations to avoid losses. Input 230 volts A.C. and output 2, 4, 6, 8, 10 and 12 V D.C.
