A new brochure describing the range of dynamic braking resistors (DBRs) from Cressall includes helpful rating curves to aid selection by users.
Self-contained and fully variable to match different power sources, the load bank is designed for easy handling and operation by a single engineer.
At 50 V, current settings from 210 A down to 0.6 A can be set in nine switched steps, with fine adjustment provided by a 0.6-5 A variable setting.
The unit can be used at lower voltages with a corresponding reduction in power.
Inside the load bank, resistance is provided by Cressall's ni-chrome elements, which have a low temperature coefficient to ensure consistent accuracy during long periods of use.
Cooling is provided by four built-in fans which are powered by the test load, removing the need for an additional supply.
For extra safety, an audible alarm is triggered should overheating occur.
The load bank is easily controlled by nine on/off switches for current adjustment and a variable resistor for fine adjustment between 0.6 and 5 amps.
A 1.5% shunt allows current measurement when an ammeter is connected to the unit's 4mm banana socket.
The resistor elements are insulated to 750V and the unit is protected by internal 250 A fuses.
The DC220 has an aluminium enclosure to keep weight to a minimum, as well as side handles and omni-directional castors to aid manoeuvrability.
The dimensions of the unit are 535 mm x 285 mm x 495 mm high.
