Commercial-Grade Dual Technology Occupancy Sensors
The Enerlites MDC-50V and MDC-50L deliver reliable occupancy detection for commercial environments using combined PIR and ultrasonic technologies. Ambient light level detection prevents unnecessary activation when sufficient daylight is present, ensuring energy-efficient operation in offices, classrooms, warehouses, and common areas.
Model Comparison
MDC-50V – Line Voltage Sensor
Commercial-grade ceiling mount sensor operating on 120VAC / 277VAC line voltage. Compatible with LED and fluorescent lighting systems. Direct control of lighting loads including resistive, tungsten, electronic ballast, and motor loads.
MDC-50L – Low Voltage Sensor
Commercial-grade ceiling mount sensor operating on 24V DC systems. Requires power pack supply (MPP-24, sold separately). Compatible with LED and fluorescent lighting. Supports optional vacancy mode and manual ON/OFF operation via ENERLITES 91245 momentary switch (sold separately).
