The RPS-1 is a self contained battery power source for use in conjunction with the HyperLogger™, ModuLogger and ModuLogger Mini,and other data loggers, field RTU's and field data acquisition equipment to power transducers requiring external power (e.g., strain gauges, pressure transducers, 4-20mA transmitters, etc.) over a voltage range of 3.5 - 22 VDC.

The RPS-1 contains two user configurable, rechargeable gel-cell type batteries and integral recharging cicuitry. The charging circuitry will accept AC or DC current from photovoltaic arrays, wind generators, utility sourced transformers, or other current sources. The sealed batteries are capable of operating in any orientation over a temperature range of -10 to 60C. The slide switch allows the user to configure the RPS-1with the two integral 12Vdc batteries wired in parallel (for 12Vdc maximum output voltage) or in series (for 24Vdc maximum output voltages).

Two user programmable power supply outputs are available which can source seven different regulated voltage levels from 3.5 to 22 VDC. Outputs are short circuit/over-current protected. The two power supplies can be independently programmed for output voltage as well as type of operational mode. Two modes are available: Continuous On or Automatic Operation. In Automatic Operation, the power supply is under control of an optically isolated low voltage (5VDC, 0.5mA) control input signal;. This control input interfaces directly to the Bitlogger RPS-1 control output line or one of the HyperLogger™ or ModuLogger built in digital outputs which in turn cycles the RPS's power supplies on and off, providing transducer excitation under the loggers control during a logging session. This automatic power supply cycling technique maximizes RPS-1 battery life.

Additionally, the RPS-1 can 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.

Logic Beach also offers the PSM-2 Power Supply Module family for powering sensors and transmitter loops. The PSM-2 is a smaller system that provides field programmable voltages (up to 24Vdc) from the data logger batteries. Refer to details on it's associated page.
