Dimensions of the Load Sharing Module - DC Powered - PWM Output (A) 272.70 mm (10.74 inch) (B) 215.93 mm (8.50 inch) (C) 200.66 mm (7.90 inch) (D) 213.36 mm (8.40 inch) (E) 58.42 mm (2.30 inch)The load sharing module is used to provide either droop or isochronous load sharing for the paralleled generator applications.There are three variations of the load sharing module: AC powered module with pulse width modulated (PWM) output, AC powered module with analog voltage output and DC powered module with PWM output. The 131-5459 Governor Control is the AC powered load sharing module with PWM output. The 131-5567 Governor Control is the AC powered load sharing module with analog voltage output. The 161-0797 Governor Control is the DC powered load sharing module with PWM output. Each of the PWM output modules are designed for operation with electronic engines. The analog output module is designed to operate with certain speed controls for mechanical engines.The load sharing module has an SPM-A synchronizer input. The load sharing module provides proportional load sharing with all load sensors and load sharing and speed controls.The load sharing modules receive generator power information from current transformers (CTs) and potential transformers (PTs). The load sharing modules calculate power from the generator, assuming that the voltage is constant. The load sharing modules generate an output which biases the speed reference of the speed control. The load sharing modules use paralleling lines to ensure proportional load sharing with other generators that are isochronously paralleled.
