The P series is a power-type surge protective device (SPD) designed in accordance with IEC, GB and other standards. At the instant a surge occurs, it connects the protected circuit into an equipotential system and limits the voltage to a certain level, thereby protecting the user's electrical equipment.
SPDs are mainly used to protect field devices such as transmitters, switches, frequency signals, communication equipment, RTDs and thermocouples connected in two-wire or three-wire configurations, as well as equipment in the control room such as safety barriers, I/O, DCS and PLC, from damage caused by lightning surge impulse voltages or switching overvoltages. The P series includes DC power SPD models, and the protection module supports hot swapping.

- Power supply SPD, designed to IEC and GB standards
- Connects to the equipotential system at the surge instant, limiting voltage to protect electrical equipment
- Surge protection module supports hot swapping; replacement requires no power-down or rewiring
- With operating status indication; failure status is clearly visible
- Optional remote signalling function for connection to monitoring systems (specify at ordering)
- Protects field instrument power supplies and control room safety barriers, I/O, DCS and PLC power supplies
Control cabinet power supply lightning protection
Install a power supply SPD at the cabinet incoming line to discharge lightning surges and switching overvoltages.
Field instrument 24V power supply protection
Add a DC power supply SPD to the two-wire transmitter supply circuit to reduce lightning damage rates.
