Tekbox TBOH02 / Active load, e.g., for EMC measurements

The TBOH02 is a precise, self-powered active load. It does not require a separate supply voltage and operates at 2V. It features constant resistance and constant current operation. A 10-turn potentiometer with a scale, a measurement range switch, and a precision reference allow for the precise setting of current or resistance. It can also be controlled by an external voltage. The design is entirely analog, which largely prevents the load from feeding in any conducted current—which is typically fed back to the digital components.The TBOH02 can be used not only as an active load for power supply measurements, but also as a current sink or current source for power LED testing and similar applications. It is also useful for field testing where no external power supply is available.The TBSOH02 operates from 2V to 70V. The maximum current is up to 10A, but ensure that the maximum power is limited to 25W without additional cooling. A fan accessory that plugs into the body inc
