Hochiki FIREscapeNepto EL-PM | Single Phase Under Voltage Relay | 230V AC, Mains Circuit Monitoring, DIN Rail Mount
£55.15 (inc VAT: £66.18)
Summary
The Hochiki FIREscapeNepto EL-PM is a professional-grade single phase under voltage relay designed specifically for monitoring the health of mains lighting final circuits in emergency lighting systems. This compact DIN rail mounted device provides critical voltage monitoring functionality, ensuring your emergency lighting systems receive proper mains supply.
Operating at 230V AC with a precise trip level fixed at 75% of nominal voltage (172V), the EL-PM continuously monitors your lighting circuits and provides immediate feedback to Nepto control panels when voltage drops below acceptable levels. The device features a built-in hysteresis function and quick response times under 300ms, making it ideal for commercial and industrial emergency lighting installations.

FAQ
What voltage level triggers the under voltage alarm?
The EL-PM is factory set with a fixed trip level at 75% of nominal voltage (Un), which equals 172V for a 230V AC supply. The device also features hysteresis functionality set at approximately 195V to prevent nuisance tripping.
How quickly does the relay respond to voltage changes?
The EL-PM features fast response times with a time delay (t1/t2) of less than 300ms. There is also a power-on delay of approximately 1 second (worst case 2 seconds) to prevent false alarms during startup.
What are the output contact ratings?
The SPDT relay output offers multiple ratings: AC1 250V 8A (2000VA), AC15 250V 5A (normally open) and 3A (normally closed), and DC1 25V 8A (200W). The contacts are rated for ≥150,000 operations at rated load.
Can this be used with non-Hochiki emergency lighting systems?
While designed specifically for integration with Nepto control panels, the EL-PM provides standard relay contacts that can interface with other emergency lighting control systems that accept voltage-free contacts for mains failure indication.
What is the power consumption of the device?
The EL-PM has very low power consumption at less than 8VA maximum, making it suitable for continuous operation without significant impact on your electrical installation.
What are the environmental operating limits?
The device operates reliably in ambient temperatures from -20°C to +60°C with relative humidity up to 95%, making it suitable for most commercial and industrial environments.
