Power Supply Devices

FAULT DRIVEN POWER SUPPLY

Monitor & Protect Control Circuits

Under normal load conditions the fault driven power supply uses the upstream voltage source to charge storage capacitors to form a DC bus. Under remote fault conditions the local voltage may fall, but this generally leads to an increase in current flow. This current is used as an energy source to supplement the available internal bus voltage maintained on the capacitors.

DC-DC POWER SUPPLY

The NEPEAN Power DC-DC Power Supply is designed by engineers with extensive knowledge and experience. The DC-DC Power Supply is designed and manufactured to ensure safety in mining and industrial industries. The DC-DC Power supply is cost effective and reliable and boasts many convenient features.

MACHINEWATCH POWER SUPPLY

The NEPEAN Power Machinewatch Power Supply has been designed by experienced engineers. The Machine Watch Power Supply has been designed to allow maximum safety in mining and industrial environments, as well as being cost effective.

AC POWER SUPPLIES

NEPEAN Power supply a wide range of AC to AC and AC to DC Power Supplies for mining and industrial markets. NEPEAN Power has a range of typical Power Supplies used in most applications. NEPEAN caters for many different styles, voltages and wattages.

The NEPEAN Power 20V AC/DC Power Supply provides dual 20V ac and a single 20V dc from 110V, Internal 15VA transformer 20-0-20ac output and an 500mA 20V DC output.

Power Quality Devices

RECTIFIERS

The NEPEAN Power 12 Way Diode Block Rectifiers have been designed to ensure maximum safety and productivity in mining and industrial industries.

Our cost effective Rectifiers, are reliable in design and are available in two different options:

  1. 12 Way diode block – X0120
  2. 12 Way diode block – X0122

DUAL DIODE ISOLATOR

The NEPEAN Power Dual Diode Isolator (DDI) has been developed to allow simple connection of two DC Power supplies to provide a single DC Output that may then be specified redundant.

If one of the DC supplies fails the other DC supply will take over automatically, immediately providing this redundancy.

Measurement Devices

TEMPERATURE RELAY

Microprocessor controlled sending relay

The NEPEAN Power Temperature Relay is a microprocessor controlled sending relay that measures the temperature from a single PT100 RTD sensor and provides two independent SPCO relay outputs each with an individually adjustable trip threshold. The measured temperature is displayed on the front of the relay.

RTD TRANSDUCERS

STRAIN GAUGE TRANSMITTER

NEPEAN Power offers a Strain Gauge Transmitter designed to provide a simple interface from a load cell to PLC input cards. Our Strain Gauge Transmitter unit is designed for use with 4 wire load cells, either 1mV/V or 2mV/V. There is an internal jumper to select between the two.

SPEED RELAY

The NEPEAN Power Speed Relay converts a frequency input signal to a 4-20mA current loop output signal and also incorporates a change over relay contact that operates or releases when the input pulse rate is less than one pulse per second. The maximum pulse rate is adjustable via a small opening on the front panel of the enclosure. The Speed Relay counts input pulses over a pre-determined time and then converts this count into a proportional output current.

CURRENT & VOLTAGE TRANSDUCERS

The NEPEAN Power range of current and voltage Transducers are designed to provide a simple interface to PLC input cards for mining and insustrial industries.

The NEPEAN Power Current and Voltage Transducers provide a 4 to 20mA signals suitable for taking to a PLC analog input card.

TEMPERATURE TRANSDUCER

Temperature Sensor Monitor

The NEPEAN Power 4 Way Multiplexer, Temperature Transducer, is an easy method of monitoring 4 temperature sensors with a single 4-20mA loop input device. The Multiplexer will directly interface with 4 x PT100 RTD sensors without the need for any other transducers or power supplies. The output from the multiplexer is a 4-20mA signal scaled as 0 to 150 degrees C.
