Introduction

This particular Load has been designed to operate with 48V and 50V, (24 or 25 cells at 2V each), battery systems and is extremely cost effective.

The load is continuously rated at 200 Amps at up to 60V DC, i.e. 12kW. The standard model has constant current operation. There is an option available for Constant Power, Constant Resistance and Constant Voltage. 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.

As standard there is an in-built LVD, (Low Voltage Disconnect). It is possible to select the “End Voltage” for both 48V and 50V systems with an equivalent “End Voltage” per cell from 1.55V PC up to 1.90V PC. When enabled the load monitors the overall battery Voltage and when it drops to the “End Voltage” it will automatically disconnect the load and the current will drop to zero. Thus, the Load now becomes an intelligent Load, in that if it is left unattended it will prevent deep discharge of the batteries and hence prevent any possible damage to them.

When this load is used in conjunction with the “Manatronics Data Logger DLM-09”, (which is recommended), the “End Voltage” will be programmed from the Logger and this will automatically disconnect the load when the Logger senses that the “End Voltage” has been reached. This feature will override the LVD in the load.

The Load is completely powered from the Batteries under test, i.e. no mains supply is required. Therefore tests are not terminated part way through by a temporary mains power outage. The unit uses forced air cooling. The Load is housed in a compact, rugged case with carrying handles and is ultra-lightweight for the power rating and is also completely portable. The Load may be left on site, unattended, for an extended period of time, if required.

The case has various rear panel connectors and the front panel has two LCD 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, easy to use and suitable for field use. It is thermally safe and has fan fail detectors on all fans together with air blockage detectors. The DC input is fused and overvoltage protection is included. The DC power connection is via an Anderson SB 350A 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).
