General Description

The ultra-compact and competitively priced Delta Sync DIN Rail DRS-12V50W1N☐power supply is designed for industrial applications

requiring highly reliable power supply that must fit in a small space. The Sync series operates with universal AC input range and offers

full power up to 55°C. The output is adjustable from 12-15 volts, and can support up to 3000 microfarads of load capacitance. A green

LED indicates output is present. The design is certified according to IEC/EN/UL 60950-1 Information Technology Equipment (ITE) and

UL 508 Industrial Control Equipment (ICE). The series is also fully compliant with RoHS Directive 2011/65/EU for environmental

protection. NEC Class 2 and Limited Power Source (LPS) approvals are available for this product.

Engineering Data

Output Load De-rating VS Surrounding Air Temperature

Output Load De-rating VS Input Voltage

Note

1. Power supply components may degrade, or

be damaged, when the power supply is

continuously used outside the shaded region,

refer to the graph shown in Fig. 1.

2. If the output capacity is not reduced when the

surrounding air temperature >55

°C, the

device will run into Over Temperature

Protection. When activated, power supply will

latch off, until the surrounding air temperature

is lowered or the load is reduced as far as

necessary to keep the device in working

condition, and require removal/re-application

of input AC voltage in order to restart.

3. In order for the device to function in the

manner intended, it is also necessary to keep

a safety distance of 80mm (3.14 inch) above

and below the device as well as a lateral

distance of 25mm (0.98 inch) to other units

while the device is in operation.

Depending on the surrounding air

temperature and output load delivered by the

power supply, the device can be very hot!

5. If the device has to be mounted in any other

orientation, please contact

info@deltapsu.com for more details.

Assembly & Installation

The power supply unit (PSU) can be mounted on 35mm DIN rails in accordance with EN60715. The device should be installed with

input terminal block at the bottom.

Each device is delivered ready to install.

Mounting

Safety Instructions

Dismounting

Fig. 2.1 Mounting

Snap on the DIN rail as shown in Fig. 2.1:

1. Tilt the unit slightly upwards and put it onto the DIN rail.

2. Push downwards until stopped.

3. Press against the bottom front side for locking.

4. Shake the unit slightly to ensure that it is secured.

– ALWAYS switch mains of input power OFF before connecting and

disconnecting the input voltage to the device. If mains are not turned

OFF, there is risk of explosion / severe damage.

– To guarantee sufficient convection cooling, keep a distance of

80mm (3.14 inch) above and below the device as well as a lateral

distance of 25mm (0.98 inch) to other units.

– Note that the enclosure of the device can become very hot depending

on the surrounding air temperature and output load connected to the

device. Risk of burns!

– The main power must be turned off before connecting or disconnecting

the wires to the terminals!

– DO NOT insert any objects into the device.

– Dangerous voltages present for at least 5 minutes after disconnecting

all sources of power.

–

The power supplies unit should be installed in minimum IP54 rated

enclosure.

–

The power supplies are built in units and must be installed in a cabinet

or room (condensation free environment and indoor location) that is

relatively free of conductive contaminants.

Fig. 2.2 Dismounting

To uninstall, pull or slide down the latch with screw driver as

shown in Fig. 2.2. Then slide the power supply unit (PSU) in

the opposite direction, release the latch and pull out the power

supply unit (PSU) from the rail.
