Description
Genrad 1570-AL 50 Amp Servo-Type Line Voltage Regulator 115V 60 Hz - As Is.
- Handles up to 500 Amperest on Short-Period Overload
- Holds Live Voltage Constant to +/- 0.25%
- No Waveform Distortion
- Holtzer Cabot RBT 2407 115 VAC 26 RPM 12 WATTS Motor
- Regulator Voltage: 115, Input Voltage: 90-110% Volts per second: 10
- Motor P/n: 4218KR. 60 CY, 12 Watts, 30 Torque OZ. IN. 30
- Genrad General Radio Company
- Has the following tubes slots: 5651, 12AX7, 12AX7, 5727, 5727 (only empty slot is a 5727)
- We have determined that the unit's missing tube is a 5727. The two 5727 tubes appear to each control one direction of the output voltage regulators. As the adjustment screw is moved, an on-board motor adjust the variac automatically. Since only one tube is installed it will only adjust in one direction. We have tested it by moving the tube to the empty slot and found the working direction changes. It appears to test GOOD, but is incomplete.
- With the input voltage at 123 Volt AC, the output voltage was adjustable from 99.9 to 128.5 Volt AC.
