The 4445 Deckmount Converter by Parallax Power Supply is a three current stage 45 Amp converter charger. The new innovative design invites more airflow and allows key components to operate cooler and in return, last longer. The 4455 comes standard with a 120VAC 15 amp line cord. It is built with a steel enclosure and has a durable powder coat finish. Can be upgraded to TempAssure™ technology by installing the Parallax 4400TAU module to maximize battery charging.
