UC1838A UC2838A UC3838A
Magnetic Amplifier Controller
FEATURES
• Independent 1% Reference • Two Uncommitted, Identical Operational Amplifiers • 100mA Reset Current Source with –120V Capability • 5V to 40V Analog Operation • 5W DIL Package
DESCRIPTION
The UC1838A family of magnetic amplifier controllers contains the circuitry to generate and amplify a low-level analog error signal along with a high voltage-compliant current source. This source will provide the reset current necessary to enable a magnetic amplifier to regulate and control a power supply output in the range of 2A to 20A. By controlling the reset current to a magnetic amplifier, this device will define the amount of volt-seconds the magnetic amplifier will block before switching to the conducting state.
