Description

DRS-480 is a 480W AC/DC DIN rail type security power supply series. In addition to the primary output, there is an additional charger circuit that will automatically adjust charge current depending on the primary output current. DRS-480 accepts the universal input between 90VAC and 305VAC, and supports output 24VDC, 36VDC, and 48VDC nominal systems. With high efficiency up to 93.5%, it can operate with free air convection cooling under -30C through 70C ambient temperature. In addition to the key protection features such as overload protection, over voltage protection, battery low voltage disconnect, and battery reverse polarity protection, the DRS-480 also provides Form-C contacts and LED indicator alarm signals for AC-fail, battery low, charger fail, and DC-OK to allow easy integration into security systems that comply with local alarm codes.

※ SBP-001 is a programmer, particularly for MEAN WELL’s various programmable battery charger models to program the parameters of charging curves, such as the Constant current (CC), tapper current(TC), Constant voltage (CV), float voltage (FV) and so on, to accommodate the diversified battery specification in industry. With the design accounting for simplicity and convenience, users can easily configure MEAN WELL’s programmable battery chargers with SBP-001 programmer and the computer; all of the setups are able to be finished easily by the means of the specific software.
Note:

Tapper current(TC) default is 10%, can be fine tuned from 2% to 30% by SBP-001 with computer or CANBus Interface.
Please contact MEAN WELL for more details.

Communication interface

Charging parameters can be modified by MODBus (Built-in) or CANBus(optional) communication commands. For details, please refer to: http://www.meanwell.com/manual.html

Power Boost Mode

The maximum current on the load output is the 2 times the rated current for 4 minutes max. and 3 times the rated current for 4 seconds max. For example (48V model):
Output load

Battery temperature compensation

To exploit the temperature compensation function, please attach the temperature sensor(NTC) which is enclosed with DRS-480, to the battery or the battery’s vicinity.
DRS-480 is able to work normally without the temperature sensor(NTC).

The compensation parameters included Disable, -3, -4 and -5mV/ ℃ /Cell .It can be modified by communication command of CANBus, MODBus. The factory default value is -3mV/ ℃ /Cell.

It will be regarded as normal temperature and will not be compensated when temperature compensation resistance is not connected; And temperature compensation will only compensate lead-acid battery, not lithium iron battery.

The range of temperature compensation is 0-40℃ , normal temperature 25℃ is the central value, no compensation; When the temperature is < 0 ℃ or > 40 ℃, the current temperature compensation value will be limited to 0 ℃ or 40℃.
24V model as an example
Assuming that V =28.8V, temperature compensation set to -5mV/℃/Cellby communication, TEMP_bat is NTCtemperature detection.
boost
The compensating voltage can be calculated by the following equation:
V =28.8V-5mV(TEMP_bat -25℃)12Cell
boost_comp
Max. compensation voltage:
V =28.8V-5mV(0℃-25℃)12Cell=30.3V
Min. compensation voltage:
V =28.8V-5mV(40℃-25℃)12Cell=27.9V

Suggested Application

Backup connection for AC interruption
- Please refer to Fig2.1 for suggested connection.
  The power supply charges the battery and provides energy to the load at the same time when AC mains is OK. The battery starts to supply power to the load when AC mains fails.
Backup time
Backup time depends on:
※ from the load current
※ from the size of the batteries.
The following table is an example (battery capacity at C10 discharge rate)Battery
