General Radio 1265A

The 1265A Adjustable DC Power Supply supplies dc bias for the 1633-A Incremental-Inductance Bridge. Its characteristics include wide ranges of current and voltage, a passive low-impedance output circuit that will pass high alternating currents, and a choice of voltage or current regulation. The instrument has four voltage ranges and four current ranges and will deliver its maximum rated power of 200 watts to 8, 80, or 800 ohms. Range switches are interlocked to prevent most likely overload situations. In addition, an electronic circuit prevents damage from overload. Rackmounting. Regulation: 1% Rating: 12.5, 40, 125, 400 Vdc @ 0.16, 0.5, 1.6, 5 A in any combination up to 200 W.
