In [Dave’s] latest episode of the EEVblog he takes a look at constant current dummy loads. These are used to test power supply designs and instead of just chaining resistive loads together every time ...
This dummy-load circuit, which is useful for testing power supplies and power amplifiers, is based on the Maxim MAX6006 voltage-reference IC and MAX480 operational amplifier. This dummy-load circuit ...
At the NAB show next month, Altronic Research will show its Model 6606/12, a convection-cooled resistor load. The OmegaLine Models 6606 and 6612 are terminators for 50-ohm coaxial transmission line ...
