The DRS-480 series from Mean Well are UPS systems with AC input and DC output.
When mains power is available, the unit provides a stable output while simultaneously charging the batteries.
In the event of a power failure, it maintains the output powered by the battery. These power supplies are suitable for security applications, access control, and any application that must continue operating even during a power outage.
The DRS series offers the functions of a power supply, battery charger, and DC UPS, as well as... as battery monitoring.
The alarms are designed to comply with EN54-4, UL2524, NFPA 1221 and GB17945 with adjustable parameters via a communications interface.
It has a relay with normally open or normally closed contact.
Includes MODBus communication protocol for equipment configuration and monitoring.
The battery charging curve can be configured using the free PC software and the SBP-001 communication interface (not included and only with the CANBus version).
Charging can be configured in 2 or 3 stages.
The charging current can also be configured using a potentiometer between 20% and 100% of the maximum charging current.
The output current is divided between the connected load and the batteries, always giving priority to the load; that is, if the powered equipment consumes more power, the output will be reduced.
The battery charging current is adjusted to prevent critical loads from shutting down. When the load level decreases, the batteries will recharge more quickly according to the programmed settings. The DRS-240 series DC UPSs offer maximum reliability for critical loads, along with advanced battery charge control to extend battery life.
