The TBOH02 is a precision self powered active load. It does not need a separate supply voltage and operates as low as 2V. Its features include constant resistance and constant current mode. A 10 turn potentiometer with dial, a range switch and a precision reference enable accurate setting of current or resistance. Furthermore it can be controlled by an external voltage.

The design is fully analog. Supply noise measurements using the TBOH02 as load will not be superimposed with additional noise in contrary to such measurements carried out with digitally controlled active loads.

The TBOH02 can not only be used as active load for power supply measurements, but also as current sink or current source for power LED testing and similar applications. It also comes handy when carrying out tests in the field, where no external power is available.

Operating voltage range: 2V ½ 70V
Maximum current: 10A
Power rating: max. 25W continuously; with additional fan 100W continuously
Ranges: 0A ½ 1A, 0A ½ 10A, 1O ½ 10O, 10O ½ 100O
External voltage control input
