Load Bank 48V / 300 Amp Load (EL18-48M)

This particular Load has been designed to operate with Telecom 48V Rectifiers and Power Supplies with output Voltages in the range of 38V to 60V and is extremely cost effective. The load is continuously rated at 300 Amps at up to 60V DC, i.e. 18kW. The standard model comes with Constant Current and Constant Power, Constant Resistance and Constant Voltage modes. The mode selection will be via the front panel. The load current is continuously variable over the entire current range. The current is controlled via two knobs on the front panel, one coarse and one fine control.

The Load is powered from the mains supply. The unit uses forced air cooling. The Load is housed in a 19 inch Rack Mount case. It can also be used as a portable Load. The case has various rear panel connectors and the front panel has two LCD digital panel meters, one for the DC input Voltage and one for the load current. There are also eight LED’s to indicate the status of the Load.

The load has been designed to be very reliable and easy to use. It is thermally safe and has fan fail detectors on all fans together with air blockage detectors. The DC input has overvoltage protection included. The DC power connection is via an Anderson SB ® Series connector on the rear panel. Monitor points are included on the front panel for access to the internal shunt. This is also provided via a D type connector on the rear panel.

Control selection is made from the front panel between “Load ON”, “Load OFF”, “Data Logger Control”, “External Input Control”, (e.g. suitable for UPS control).

The rear panel has a connector to link to the “Manatronics Data Logger DLM-09” or for an external load on / off control, (e.g. suitable for UPS control).
