Integrated Overload and Low Voltage Interrupt Module
First Claim
1. A power management module for an electrical winch system for a vehicle comprising:
- an overload interrupt module that determines an operating current of the winch system and that provides a first interrupt signal when said current is greater than a threshold current;
a low voltage interrupt module that determines a voltage of a power source and that provides a second interrupt signal when said voltage is less than a threshold voltage; and
a housing, wherein each of said overload interrupt module and said low voltage interrupt module are located within said housing.

Abstract
A power management module for a winch system comprises an overload and low voltage interrupt module within a housing. The overload interrupt determines operating current for the winch system and provides an interrupt signal when the current is greater than a threshold. The low voltage interrupt determines voltage of a power source and provides an interrupt signal when the voltage is less than a threshold. A method of operating the power management module comprises determining operating current of the winch system with an overload interrupt module and voltage of a vehicle power source with a low voltage interrupt module. The overload and low voltage interrupt modules are located within a housing. The overload interrupt provides an interrupt signal when the operating current is greater than a threshold. The low voltage interrupt provides an interrupt signal when the voltage is less than a threshold.
