Overview

What it is

The MEAN WELL DRS-240-36 is a security power supply with battery charging from the DRS-240 series (240 W All-In-One Intelligent Security Power), rated 36 V, 6.6 A, 240 W.

What it is used for

Powers 36 V security, fire alarm and public safety loads while charging a backup battery, and switches the load to the battery within 10 ms of a mains failure. Relay alarm contacts and MODBus let a panel or BMS monitor AC, battery and charger status. MEAN WELL lists applications such as public safety battery backup (red box), security systems, alarm systems, dc ups and battery detection systems.

Key features

All-in-one power supply, DC UPS, battery charger and status monitoring in one unit.
Form C relay contacts and LED indicators for AC fail, battery low, charger fail and DC OK.
Signal and alarm design meets UL2524, NFPA 1221, BS EN/EN54-4 and GB17945 requirements.
Built-in MODBus (standard model) or CANBus (CAN model) protocol.
2 or 3 stage charging selectable by DIP switch, charging current adjustable 20 to 100% by VR.
Suitable for lead acid and lithium-ion batteries.

Key Specifications

Output Voltage: 36 V.
Output Current Range: 0 to 6.6 A.
Battery Charging Voltage: Boost 43.2 V, float 41.4 V (default 3 stage curve; DIP switch presets for gel, flooded and AGM/LiFePO4).
Charging Current: 5.1 A max. (constant current), adjustable 20 to 100% by VR.
Input Voltage Range: 90 to 305 V AC; 127 to 431 V DC.
Rated Output Power: 240 W total, load and battery charging combined, load has priority; 275 W peak within 5 s.

Buying considerations

Size the unit with headroom above the connected load and check the derating information in the datasheet for high ambient temperature or low input voltage. Other models in the same series are listed on this page.

Installation considerations

MEAN WELL treats this unit as a component of the final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring and safety details are in the official datasheet linked below.
