The GMP Tools Replacement Power Supply (part 33846, Millennium part 526418) runs on 100-240 V input, giving crews a direct spare for the power unit feeding electronic accessories on GMP cable blowers and hydraulic power units. Its wide voltage range lets it work across domestic and international job sites without a separate transformer. Techs swap it in when a blower's factory supply fails, keeping the machine in service without waiting on OEM lead times. Order it with related hydraulic power unit parts and blower spares for the same equipment line.
