The 4435 Deckmount Converter by Parallax Power Supply is a three-current stage 35-Amp converter charger. The new innovative design invites more airflow and allows key components to operate cooler and in return, last longer. The 4435 is equipped with a 120VAC 15-amp line cord. It is built with a steel enclosure and has a durable powder coat finish. This product can be upgraded to TempAssure™ technology by installing the Parallax 4400TAU module to maximize battery charging.
