HP 87422A Power Supply, ±12 VDC, ±15 VDC, 70 W

The HP 87422A is a universal input, dc switching power supply designed to provide the bias voltages needed to operate HP microwave system amplifiers. These compact power supplies are ideal for integration into a system or for use on a benchtop. The two-meter dc bias cable permits the amplifier to be remotely located, allowing it to be placed out of the way or where space is not critical. The HP 87422A is a 90 watt, ±15V dc power supply designed to power the HP 83020A microwave system power amplifier. One additional ±12V dc output is provided to power a preamp such as the HP 83006A or 83017A. Included with the power supply are the necessary two-meter cables to connect to the amplifier.
