Programmable Voltage Reference Plug-In
ProDAQ 3202
The ProDAQ 3202 voltage reference card is used in the ProDAQ 3180 ultra-performance motherboards and LXI function card carriers. The ProDAQ 3202 voltage reference card is plugged directly onto the motherboard or carrier and can distribute the reference voltage to all ProDAQ function cards via two signal lines. This allows the distribution as a differential signal to overcome possible noise pick-up.

PPS Clamp Transformer
PPS2 provides power supply to the PD detectors installed on HV cable when low voltage AC power is not available. The PPS2 takes the required power directly from the High Voltage power line under monitoring by means of units clamped on the HV power cable(s).PPS2 is designed to withstand High Voltage line failure events such as temporary overload and short circuit conditions. An internal detection and self limiting circuitry guarantees that PPS2 and the connected equipment survives in case of such events.

High Frequency Transformers
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.
