The OM-220-RPS-1 contains two user configurable, rechargeable gel-cell type batteries and integral recharging circuitry. The charging circuitry will accept ac or dc current from photovoltaic arrays, wind generators, utility sourced transformers or other current sources. The sealed batteries can operate in any orientation and over a temperature range of 14 to 140F (-10 to 60C). The slide switch lets the user configure the OM-220- RPS-1 for 12 or 24 Vdc operation.
Two user-programmable power supply outputs are available that can source seven different regulated voltage levels from 3.5 Vdc to 22 Vdc. Outputs are short circuit/over- current protected. The two power supplies can be independently programmed for output voltage as well as for type of operational mode. Two modes are available: Continuous On or Automatic Operation. In Automatic Operation, the power supply is under the control of an optically isolated low voltage (5 Vdc, 0.5 mA) control input signal. This control input interfaces directly to the power supply's control output line (or other datalogger's control outputs), which in turn cycles the power supplies on and off, providing transducer excitation under OM-220 control during a logging session. This automatic power supply cycling technique maximizes OM-220-RPS-1 battery life.
The OM-220-RPS-1 can also be used as a general-purpose regulated power source for many other types of equipment (alarm systems, control systems, etc.) requiring field power in a remote environment.
