Power Supplies range at a glance

How to choose

• For fixed student voltages, the Basic PSU gives a.c. or d.c. at 2, 4, 6, 9 or 12 volts and up to 4 amps, chosen with a five-position switch.
• Where the top voltage must be limited, the Lockmaster Power Unit adds a key-operated voltage lock and gives 0-15V a.c. or unsmoothed d.c. in 1V steps up to 8.5A.
• Advanced courses needing an accurately monitored voltage or current suit the College Power Unit, which supplies 0-25V a.c. or smoothed d.c. from a rotary control.
• Electrostatics and deflection-tube work call for an EHT supply: 0-500V from the EHT Power Supply, or a continuously variable 0-5kV at up to 2mA from the EHT Power Unit.
• The Electromagnetics Power Unit gives high current at low voltage for magnetic-field investigations, and the Smoothing Unit reduces ripple from the non-regulated supplies.

Frequently Asked Questions

Q1. Which unit suits high-voltage electrostatics experiments?
The EHT Power Supply gives 0-500V and is designed for electrostatic experiments including ionisation and for driving vacuum devices such as the Deflection e/m tube. The EHT Power Unit is continuously variable from 0-5kV at a maximum current of 2mA and has a second EHT output.

Q2. How does the Bench Power Unit differ from the Lockmaster Power Unit?
The Bench Power Unit lets its a.c. and d.c. outputs run at the same time within a combined 8.5A. The Lockmaster Power Unit gives 0-15V a.c. or unsmoothed d.c. in 1V steps at up to 8.5A and adds an adjustable, key-operated Limitlock maximum voltage lock.

Q3. Which instruments here measure very small currents or voltages?
The Picoammeter measures very small currents across 9 ranges from 100pA to 1µA, selected with a rotary switch. The Microvoltmeter has a large moving-coil meter and an auto-zero facility and works as a replacement for a centre-zero galvanometer.

Q4. Which spare parts fit the lockable power units?
The Spare Part: PSU Key for Lockmaster and Ranger replaces the voltage lock key, and the Spare Part: Grey Voltage Indicator fits the Ranger and Lockmaster units. Red and black replacement terminal sockets fit the Regulated PSU, Basic PSU and Ranger PSU.
