Power Inverter Type B681

Summary: This document provides technical specifications for the B681 Power Inverter, which contains four high-current inverters. Each inverter features separate emitter connections and a permanently connected 20mA clamped load, supplemented by four additional 10mA clamped loads.

• Input Requirements: Each input requires a 2mA steady-state current at -3V, and each independent clamped load requires 10mA from a transistor collector to maintain ground.
• Output Capabilities: Each transistor can supply 32mA at ground. Internally, 20mA is absorbed by the clamped loads, leaving 12mA available for external loads (such as diode gates). Additional clamped loads can supply 7mA at -3V.
• Power Requirements: The unit requires +10V at 0mA and -15V at 130mA.
