Merawex Buffer power supply unit ZM12V12A-200B

Manufacturer's designation: ZM12V12A-200B MERAWEX. Ideal for use in uninterruptible power supplies such as alarm systems and smaller communications equipment. The power supplies also have a module for battery connection. The batteries are charged and controlled (undervoltage) via the power pack. The power packs can thus be ideally used in small UPSs with DC voltage. They are equipped with LED and relay signaling. The deep discharge protection safeguards the connected battery from damaging deep discharge. A temperature sensor allows for temperature-compensated charging of the batteries.

Functions and features:

• Single-phase input voltage 230Vac or 220Vdc
• Optical signaling
• A relay signals correct operation
• Low voltage signaling at the battery terminals
• Buffer operation with temperature compensation of the charging voltage
• Operation in automatic charging mode
• Active PFC (Power Factor Correction)
• Optical signaling of charging, battery operation, and low battery condition
