RPS-1 POWER SUPPLY FOR SENSOR EXCITATION Features • Self-contained Regulated Voltage Source Rechargeable Battery Operation • • Two Programmable Output Voltages (3.5Vdc to 22Vdc, 7 ranges) • Battery State of Charge Indicator • Easily Interfaces to data loggers, transmitters and sensors • Optically Isolated Power Supply Control ON/OFF Input • Weatherproof OVERVIEW The RPS-1 is a self-contained battery power source voltage levels from 3.5VDC to 22VDC. Outputs are for use in conjunction with the HyperLogger and short circuit / over-current protected. ModuLogger data logging and alarming systems The two power supplies can be independently from Logic Beach. It is also used in the Logic programmed for output voltage as well as type of Beach HL-200 System Base to power transducers operational mode. Two modes are available, requiring external power (e.g. Strain Gages, Continuous ON or AUTOMATIC Operation. In Pressure transducers, 4 to 20ma Loop Transmitters, AUTOMATIC Operation, the power supply is under etc) over a voltage range from 3.5 to 22 VDC. The control of an optically isolated low voltage (5VDC, RPS-1 may also be used as a stand-alone power 0.5mA) control input signal. This control input source for sensors, transmitters, data loggers or interfaces directly to a Logic Beach data logger other remote equipment requiring a regulated power control output line which in turn cycles the RPS-1 source. power supplies ON and OFF, providing transducer The RPS-1 contains two User-configurable, excitation under datalogger control during a logging rechargeable gel-cell type batteries and integral session. This automatic power supply cycling recharging circuitry. The charging circuitry will technique maximizes RPS-1 battery life. accept AC or DC current from Photovoltaic arrays, An integral State-of-Charge (SOC) indicator is wind generators, utility-sourced transformers/plug-in provided which will display an approximate Battery power supplies, or other current sources. The State-of-Charge based on battery voltage under a sealed batteries are capable of operating in any fixed load. Test is actuated by depressing a orientation and over a temperature range of -10 to momentary SOC Test Switch. 60C.
