USER INSTRUCTIONS

1) DESCRIPTION

DIN rail-mounted main switching power supply, with 85 - 264 VAC (120 - 370 VDC) input, suitable for single-phase power lines and DC lines.

2) INSTALLATION

Use DIN-rails according to EN 60715. Installation should be made vertically (see Fig. 4). For better device stability fix the rail to the wall close to the point where the

device is to be mounted. To guarantee sufficient convection, we recommend observing a minimum distance to other modules (see Fig. 3).

The product has over-temperature protection；restricted airflow will cause local temperatures to be too high, which may trigger the over-temperature protection to

restart after cooling;

To get normal operation reduce the temperature of the air surrounding the power supply, increase the ventilation or reduce the load (see Fig. 8)

3) CONNECTIONS

The device is equipped with screw terminal blocks. To avoid sparks, do not connect or disconnect the connectors before having previously turned-off input power and

waited for internal capacitors discharge (minimum 1 minute).

In order to comply with UL certification,

When the ambient temperature is ≤ 60°C, use a copper wire with a specification of ≥ 90°C

When the ambient temperature is > 60°C and ≤ 85°C, use a copper wire with a specification of ≥ 105°C;

Only use wires with a minimum insulation strength of 300 V (input) and 60 V (output).

Strip the connection end of the wire according to the instructions, and make sure that all strands of the twisted wire enter the terminal connection (see Fig. 5)

4) INPUT PROTECTION

The device input is provided with varistors against overvoltage. Input is provided with internal fuses 8A(T)/ 250 VAC, thus an external short circuit / overcurrent

protection must be provided by the end user (see Fig. 6).

For operation on a single-phase system, a protection fuse on the phase must be provided.

Surge protection: it is strongly recommended to provide external surge arresters (SPD) according to local regulations.

5) AC INPUT CONNECTION

The device can be connected to single phase AC line with rated Vin 100 - 240 VAC (see Fig. 7). Please connect the PE first.

6) DC INPUT CONNECTION

Connect L terminal to (+) positive pole, N terminal to (-) negative pole and PE terminal to GND. Rated voltage 120 – 370 VDC.

The device is also suitable for photovoltaic or wind turbine applications (see Fig. 7).

7) OUTPUT CONNECTION

Vout can be adjusted with a potentiometer to a wide range (see Fig. 1)

Check Vout before connecting the power supply to the load. With output voltage set to the max. value, the continuous [current x voltage] must not exceed the

nominal power.

8) OUTPUT PROTECTION

The device is protected against overload (OL) / short circuit (SC) / overvoltage (OV) / overtemperature (OT).

Overload (OL) hiccup mode description:

When the power supply provides 105%~150% of the rated output current, there are two protection modes. The power supply will first enter the hiccup protection mode at

a certain overload current point. The output overload current continues to increase, and the product will enter the constant current hiccup mode; (due to different input

voltages, different output voltage overload protection points are different and cannot be accurately given)

Overload (OL) enters hiccup mode 1:

When the output power is 105%~150% of the rated output power, the output voltage is the nominal voltage, keep it constant for 1s (typical value) and then turn off the

product output, and output after 10 s (typical value) Restart, the power will start on/off cycle hiccup mode until the abnormality is eliminated.

Overload (OL) enters constant current (CC) hiccup mode 2:

When the output power is 105%~150% of the rated output power, the output current continues to increase, triggering the constant current hiccup protection mode, the

output voltage drops and depends on the impedance of the faulty load circuit After the output current is constant for 1s (typical value), the output of the product will be

turned off, and the output will restart after 10s (typical value), and the power will start to turn on/off cycle hiccup mode until the abnormality is eliminated.

Short circuit (SC) enters constant current (CC) hiccup mode:

When the output load is short-circuited, the output voltage is close to 0V, the output current is constant, the power supply can provide 105%~150% constant output

current, and the product will be turned off after 1s (typical value) operation Output, the output restarts after 10 s (typical value), and then the device starts the on/off cycle

hiccup mode until the abnormality is eliminated.

Output OV circuit protection

24 V

：

overvoltage protection range 29 V – 35 V, output voltage turn off or clamp, re-power on for recover or automatically recover.

48 V

：

overvoltage protection range 56 V – 60 V, output voltage turn off or clamp, re-power on for recover or automatically recover.

OT protection:

Turns off the device if the internal temperature exceeds a safe limit. The device restarts automatically after cooling down. To recover to normal operation, reduce air

temperature surrounding the power supply, increase cooling or reduce load.

9) FEEDING DC MOTORS

It is possible to feed DC motors considering that when a motor starts-up under effort its consumption is much higher than the nominal current and it can trigger

overcurrent protection. (See accessory device.)

NOTE: motors can generate high conducted noise on the DC line. Therefore, it is not recommended to feed on the same line motors and equipment sensitive to noise.

10) OPERATION WITH BATTERY

When a battery is connected in parallel to the Output for backup purposes (see accessory device).
