The PEC3874B ferroresonant rectifier floats or equalizes lead-acid battery strings of 23 or 24 cells comprised of either the wet or sealed battery design. The rectifiers will facilitate positive or negative load share when used together in a system. An AC input circuit breaker is equipped on the front of the PEC3874B for protection, or to allow the user to easily power down the unit. Analog meters are provided to monitor voltage and current of the rectifier. The reduced overall size of each unit allows more rectifiers to be installed in a given space, while conduit knockouts located on both the top and front of the unit allow for flexibility. The controlled ferroresonant design of this product provides an efficient and cost effective approach to power conversion with the benefits of enhanced reliability, reduced TIF and RFI, improved power factor, and high immunity to transients.

The PEC3875B controlled ferroresonant rectifier floats lead-acid battery strings of 23 or 24 cells comprised of either the wet or VRLA battery design and supplies current to the load. The Universal Load Sharing circuit allows the rectifier to proportionally load share with ALL Major Brands of Control Ferro Rectifiers making it an excellent choice for adding to or replacing rectifiers at a site. Local AC On/Off, DC output fuse, Float/Equalize and Test switches, Voltage and Current meters along with adjustments for Float and Equalize voltages are provided to facilitate installation, operation and maintenance. The Universal Controller Interface allows the rectifier to work with a variety of Conventional and Intelligent Interfaces (PECO II, Marconi, Tyco, etc.*). Connectors accept standard interface cables for Tyco CCS, MCS and Galaxy* (pending) controllers. The reduced overall size of each unit allows more rectifiers to be installed in a given space, while conduit knockouts located on both the top and front of the unit allow for flexibility.
