This model has been developed to accommodate testing of both 48V and 24V telecommunications power systems or Power Supplies. It is also useful as a general-purpose variable Load. Its founding principle is simplicity – ease of use, enhanced reliability, greater value for money and wider applicability.

This Load is continuously rated to operate fully over the specified Current and Voltage ranges.

The standard model gives constant current control, with a differential 0 – 5V input for simple control systems, or can be paralleled for use in large systems.

Constant Power, Resistance and Voltage modes are standard, as well as full ATE/remote control. The D9 connector on the rear panel provides access to the analogue demand input, and all logic controllable functions and status lines.
