FEATURES

 

DESCRIPTION

The Broman Portable Load Boxes are intended primarily for testing battery banks.  They employ a compact array of power absorbing elements mounted in a rectangular duct-like case with a heavy duty fan at one end.  Heated air emerges in a concentrated jet which can be directed, through an open doorway, out of doors.   Mounted on top of the case is a control box containing a master circuit interrupt switch, loaded switches and ammeter.  The load current can be varied by means of toggle switches in increments as low as 1 ampere.  Two-way overload protection is provided by a thermal switch which senses overheating and by an air flow switch which senses loss of cooling air.  Operation of either of these switches will trip the master circuit interrupt switch.
