The DRS series is a DIN-rail type, digital security power supply launched by
MEAN WELL. It integrates DC output, battery charge, uninterruptible
power source (DC-UPS) and Modbus digital communication in tiny
dimensions, thanks to microelectronics. The DRS series accepts the
universal input between 90VAC and 305VAC. 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 series also provides Form-C contacts and LED indicators as alarm
signals for AC-fail, battery low, charger circuit fail and DC-OK, allowing
easy integration into security systems. This series has 2-stage and 3-stage
charge curves selectable by DIP switch, charging curves can also be
programmed by SBP-001 as well as manual adjustment through a
potentiometer (ADJ) on the panel to change charge current from 20% to
100%. The DRS series is suitable for Lead-acid and Lithium batteries with
various capacities and can be remotely monitored by communication. The
DRS series is a great solution for smart cities and building securities.

1. Safety Guidelines
1
nRisk of electrical shock and energy hazard.Allfailure should be examined
by a qualified technician.Please do not remove the case of the power
supply by yourself.
nRisk of electrical arcs and electric shock(danger to life).Connecting both
the primary and the secondary sides together is not allowed.
nRisk of burn hazard.Do not touch the unit in operation and shortly after
disconnection.
nRisk of fire and short circuit.The openings should be protected from
foreign objects or dripping liquids.
nOnly install the unit in a pollution degree 2 environment(Note.1).
nPlease do not install the unit in places with high moisture or near the
water.
nThe FG( )must be connected to PE(Protective Earth).
nDisconnect system from supply voltage:
Before commencing any isstallation,maintenance or modification
work:Disconnect your system from supply voltage.Make sure that
inadvertent connection in circuit will be impossible.
nFor continued protection against risk of fire,replace only with same type
and rating of fuse.
nNotices for battery application
a. Make sure charging voltage and current meet battery s specification.'
b. Refrain from connecting new and old batteries in series.
c. The cables between power supply and battery should be kept as short
as possible to prevent excessive voltage drop (suggested cable length:
50cm~ 1000cm). Too much voltage drop will lead to longer charging
period.
d. The power supply is suitable for lead-acid batteries (flooded water
type, gel colloid type, AGM adsorption glass fibber) or (lithium ion,
lithium manganese, lithium ternary...etc.
Note.1: Pollution Degree 2 applies where there is only non-conductive
pollution that might temporarily become conductive due to
occasional condensation.Generally refer to dry,well-ventilated
locations,such as control cabinets.

32.Installation Procedures
3.3 Cable Selection
Wire connections should be as short as possible. Make sure that
suitable wires are chosen based on safety requirement and rating of
current. Small cross section will result in lower efficiency, less
output power and the wires may also become overheated and cause
danger. For selection, please refer to the following table.
3
Step 1. Please connect AC input cables, DC output cables, battery
charging cables, and RJ-45 communication cables(if used)
to the terminal blocks of this product.
Step 2. Make sure cables well connected,all are then feeds the AC
energy to the supply.
Step 3. After power-on, make sure LED indicates in green or orange,
mean normal operation. （LED status refer to Chapter 4.3）ing

34.Battery Selection
Battery types: Lead acid or lithium ion batteries
Battery capacity: Please refer to the following table
Battery capacity recommendation
NOTE:
1.Using batteries with greater capacity than recommendation will not
damage the battery, but extend charging period is expected.
2.Please contact battery supplier for charging characteristics if it s'
not clear.
35.Serial and parallel connection of battery
●:Serial connection When connect
2 batteries in series, it doubled
the output voltage, but the
capacity remains.
EX: 2pcs of 12V 100AH in series,
become a 24V 100AH battery.
●Parallel connection: When 2
batteries connected in parallel,
output voltage remains, but the
capacity .becomes doubled
EX: 2pcs of 12V 100AH connect in
parallel,become a 12V 200AH
battery.

in C.C, C.V and F.V will turn off after 2-stage of chargingcluding not
finished. User can choose between 2- or 3-stage according to thes
demand.
Note: DC UPS function will not be achieve in 5 seconds at first start-up.

In the initial stage of charging, the charger charges the battery with the
maximum current, and the fan is ON (built-in fan model). After a period
of time (depending on the battery capacity), the charging current
gradually decreases. When the charging current drops to 10% of the
rated current, LED indicator lights up in green, indicating that the
charging process is complete. If the charging is finished, power supply
will turn off the output of charger, but remain the output of load.s

Users can set charging parameters via Modbus or CANBus(optional)
including constant current, voltage, float voltage, tapper current,
battery temperature compensation and charge time, etc.
Refer to chapter 5.4 for details.
SBP- 001 is a smart battery charging programmer developed by
MEAN WELL, which can set the charging curves of the DRS series
through editing software. SBP-001 provides functions such as
charging curve adjustment and battery temperature compensation.
Please set the DIP switch pin to Default, programmable (PIN2: OFF:
PIN3 : OFF) before use. onfiguration and software interface areC
shown as below. Please refer to SBP-001 Smart Battery Charging“

This device supports Modbus RTU with the master-salve
principle. During data transfer, please follow the principle of
first sending the High byte and then the Low byte except Error
Check(CRC-16 checksum).
5.4.1.1 Modbus specifications
Modbus communication interface
The Modbus protocol can be used to read status and control
settings of the all-in-on security powers (slave), including
operation on/off, output voltage/current adjustment and internal
temperature reading. In addition, charge curves and relative
charge parameters of constant current, constant voltage, float
voltage, tapper current, battery temperature compensation and
charge time. Output can also be adjusted when set in the charge
mode.

Function code (1byte): The function code is used to tell the slave what
kind of action to perform.

dependent on different function codes.
Error Check (2bytes): utilizes CRC-16.

5.4.1.4 Additional Address Definition
Additional address is the slave ID of the device. Each DRS unit
should have their unique and own device address to communicate
over the bus. Slave ID is set by CN12 (A0~A1)
The device address is set as follows:

5.4.1.5 Function Code Description
The main purpose of the function codes is to tell the slave what kind
of action to perform. For example, function code 03 will query the
slave to read holding registers and respond the master server with
their contents.
Function Code of DRS as follow：
Read Holding Register
Read Input Register
