Http:/ gi7b.gs35b.com. Power Supply Dummy Load. Using the switches the current can be varied from a single bulb to all 12 bulbs on either load which essentially means there are two load banks, one with a load range of about 600 ma to 7.5 amps and another with a load range of approximately 2.1 to 25 amps. The two could be combined externally to provide a maximum load of 32.5 amps. Click the small pictures to open a large picture in a new browser window). Close-up of the bulbs and switches.
