| Description | |
A six-decade resistance substitution box designed for use in educational establishments.
| Code: IV8000
The Powerbase V8 comes with a high power rotary transformer and a high specification toroid transformer replaces the original chassis transformer. The unit supplies 0-20V smoothed dc and 0-16V AC at 8 amps. The output is continuously variable and protected by a panel mounted thermal cut out. An output limiter is fitted which allows the user to preset the maximum voltage available. |
A compact power supply offering 2, 4, 6, 8, 10, and 12 volts at currents of up to 5A. Both dc and ac outputs may be used simultaneously up to the rated output. The output is protected by a push button cut-out. The unit is 2A fused on the back panel and comes complete with a moulded mains lead and plug. 4 units are designed to fit in a shallow Gratnell tray.

- Simulates resistances from 1Ω to 999,999Ω in 1Ω steps
- The required resistance is set by selecting the correct value from six rotary decade switches which clearly indicate the value selected by the student
- An additional 1kΩ resistor is provided connected between one of the terminals of the internal resistance and a third terminal so the unit can be used as an accurate potential divider
- All outputs are on 4mm terminals with 4mm sockets
- Housed in a tough ABS box with non-slip rubber feet
- Voltage rating 250V
- Power rating 600mW
- Dimensions 110 x 75 x 50mm
- Designed and manufactured in the UK
