TekBox TBOH02 Self Powered Active Load

Benefits of the TekBox TBOH02 Active Load, Current Sink or Source

• Self-powered, precision active load.
• Can also be used as current sink or current source for power LED testing and similar applications.
• Suitable for EMC test setups of DC/DC converters without adding any emissions of its own.

TekBox TBOH02 Self Powered Active Load

The TekBox TBOH02 is a precision self powered active load. No separate supply voltage is required. The TBOH02 operates as low as 2 V and features constant resistance, constant current mode and others. The TBOH02's 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 TBOH02's design is fully analog, so 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).

• Operating voltage range 2...70 V.
• Maximum current 10 A.
• Power rating max. 25 W continuously; with additional fan 100 W continuously.
• Ranges 0...1 A, 0...10 A, 1...10 Ω, 10...100 Ω.
• External voltage control input.
• Useful for tests in the field, where no external power is available.
