ONLINE BATTERY CHARGER FOR SOLAR

General Details

The model MECH OBCS is designed to deliver power line isolated uninterruptable power for precision instrumentation systems using an alternate energy source, such as solar panel. Alternate power sources are ideal for low power instrumentation systems at remote monitoring sites where commercial power lines are not available. Most of the alternate energy sources can be directly connected to the charger input. The MECH OBCS will operate in harsh environments, and has unique capabilities for remote power system monitoring, a cost saving feature for remote system installations.

The primary function of the MECH OBCS is to maintain a SMF battery in a temperature compensated floating fully charged state. When maintained in this state, SMF batteries can have a useful life of many years. Battery life decreases with repeated discharge cycles and increasing depth of discharge. The most common alternate energy source, the photovoltaic panel, provides durinal charging. Therefore, the objective is to size the battery and load so that only a minor portion of the battery capacity is consumed overnight, avoiding deep discharges. The MECH OBCS charges the battery as efficiently as possible while the charge input is active, without overcharging the battery. Overcharging will drastically reduce battery life.

When the alternate power source is not producing power, the external equipment draws energy from the battery. When input power is restored, the battery charges at the appropriate rate until it is completely charged, at which time the charger switches to the float mode.

Features
  • MECH OBCS delivers up to 30 A of output current at 12VDC
  • Versatile charger input ranges 12-20 VDC.
  • Charge level monitor provides an indication of the battery charge, battery low on LED.
  • Power failure indication on LED with potential free contact.
  • Reverse polarity indication for output.
  • Output over load protection.
  • Over voltage protection for Input and Output.
Applications
  • Systems requiring Uninterruptable DC power, using an alternate energy source, typically solar
