1761 CAL

The 1761 CAL from B&K Precision is a triple output (A, B & C) DC power supply with dual 4-digit LED displays. It is a high quality, general purpose DC power source. The power supply provides two main supplies and a third auxiliary output. It offers three independent outputs with coarse and fine adjustment knobs for volts. The 4-digit LED display offers 10mV (±(0.5% rdg + 9 digits) and 1mA (±(0.5% rdg + 9 digits) providing capability to set voltage and current values more accurately than 3-digit displays found in most comparable power supplies. Two large panel mounted LED meter displays can monitor either output current or output voltage of each supply. This model exhibits excellent regulation and low ripple characteristics. The circuit design incorporates pre-regulator which greatly reduces internal power dissipation at low output voltages. The features and versatility of the unit, especially triple output and tracking features, make it an ideal for engineering lab applications.

Warnings

There may be great danger of electrical shock if the power supply output is connected to an external high voltage. Some equipment being powered may contain high voltage and present a shock hazard.

Notes

Use only a polarized 3-wire AC outlet. This assures that the power supply chassis, case and ground terminal are connected to a good earth ground and reduces danger from electrical shock.
