200Vdc External Voltage Bias is an AC DC Test equipment or a test fixture, suited for industrial use. It can endure large currents. Its dimension is 150x97x145 (W/H/D). When an external energy basis is applied to a P-N junction, this is known as biasing or a bias voltage. This very method can boost and reduce the barrier potential of the junction. Consequently, the reduction of the same results in the returning of current carriers to the depletion region. 200Vdc External Voltage Bias is provided with maximum voltage of +200 V peak max. (AC+DC).
