Sterling Power PCU2420 — Pro Charge Ultra 24V / 20A Marine Battery Charger
The Sterling Power PCU2420 is a marine-grade AC battery charger built for 24V systems requiring reliable, intelligent shore power charging across up to three battery banks simultaneously. At 20A output it’s a capable unit for smaller 24V vessels, commercial vehicles, and off-grid setups where moderate charge rate and a compact footprint are priorities.
The Pro Charge Ultra platform has been refined over years of real-world marine use and won the innovation award at IBEX 2010. It runs on any global AC power source between 80–270V and uses Power Factor Correction (PFC) technology to reduce input current draw, generate less heat, and minimize electrical noise. A full 4-stage charge profile — bulk, absorption, float, and equalization — is applied automatically, with multiple battery type profiles including support for AGM, gel, flooded lead acid, and lithium. A battery temperature sensor is included for voltage compensation and thermal protection.
The PCU2420 is conformal coated for salt air and humidity, conforms to the ABYC drip test when mounted correctly, and uses non-ferrous metals throughout. Optional remote control (PCUR) available separately.
