1.3 Operation : The part of the device which is numbered as 1 in Figure-1 is the input voltage
connection point of PS-362 and it is shown with L (Line) and N (Neutral) on the device body. Connect
the supply voltage to these points. The part of the device which is numbered as 2 in Figure-1 is the DC
output connection point of PS-362 and its polarity is shown with + and - on the device body. PS-362
supplies adjustable DC voltage from these connection points. When supply voltage is applied to PS-362,
the yellow LED which is numbered as 5 in Figure-1 will light up. When this is LED is lit, it indicates that
PS-362 is working and it generates an output voltage. The part of the device which is numbered as 4 in
Figure-1 is the DC voltage adjustment trimpot of the device. After the device has been energized, the
output voltage is increased by turning the adjustment trimpot clockwise and is decreased by turning
the adjustment trimpot is turned counterclockwise. This way, the output voltage can be adjusted in the
specied range.The device will turn itself o to protect itself during cases of overload, overheating and
shortcircuit at the output contacts. When the error state is resolved, it will activate itself
automatically.
2- Block Diagram
2.1 Input (1)
- The part which is numbered as 1 in Figure-2 is the Line and Neutral supply inputs of PS-362.
- 100-240V AC input voltage can be connected by using the L and N terminals.
- 110-350V DC input voltage can be connected by using the L and N terminals.
- The device is protected by an internal fuse. However, an appropriate external fuse can be used if a DC
supply voltage is going to be applied to the device.
2.2 Output (2)
- The part which is numbered as 1 in Figure-2 is the DC voltage output of PS-362.
- Positive and negative parts of the output voltage are shown with (+) and (-).
- Output voltage is 24V DC.
- Output voltage can be adjusted between 21.6-27.6V DC values by using the adjustment trimpot on
the device.
- Device output is protected against short circuit.
- When the output is shorted circuited, device turns o completely and turns on again after the short
circuit condition is resolved.
- The device switches to protection under nominal load during high temperature. The red LED lights
up together with the yellow LED during protection. Until the device is cool again, it doesn’t generate
an output voltage.
- The device can operate up to an ambient temperature of +55 C.
3.3 Contact Output (3)
PS-362 devices have contact output. When the device is operating normally, contact output is short
circuited. During overload or thermal protection situiations, contact output is open circuited. During
overvoltage on output, the device waits for this error to be resolved by constantly turning itself on and
o. During this, contact output will be constantly open and short circuited at each try.
PS-362 has LED indicator (Parts 5 and 6 in Figure-1).
- When there’s no energy : Output OK and Overload LEDs are o.
- Normal operation mode : Output OK LED is on.
- Short circuit : Output OK and Overload LEDs are o. If short circuit situation is resolved, the
device starts to work again.
- Overload : If overload is drawn from device at normal temperature, Output OK and Overload
LEDs turn o. The device makes blinks. When the load condition returns to normal, the device
starts to opening again.
- Overheating + Overload : All LEDs turn on. Device cuts the supply, doesn’t generate voltage.
- Overvoltage on Output : Output OK LED blinks.
3- Connection and Mounting
3.1 Wire Connection
- AC Input (1): Under nominal load, PS-362 draws maximum 0.9A AC and minimum 0.4A AC.
Wire thickness must be selected according to these values. Maximum 14 AWG stranded
wire (2.5 mm) or 12 AWG solid wire (4 mm ) can be connected to the input terminal.
- DC output (2): Output current is 1.5A DC. Wire thickness must be selected according to
this value. Maximum 14 AWG stranded wire (2.5 mm ) or 12 AWG solid wire (4 mm ) can be
connected to the output terminal.
- Contact output (3): Contact current is maximum 10A AC. Wire thickness must be selected
according to this value. Maximum 14 AWG twisted wire (2.5 mm ) or 12 AWG solid wire
(4 mm) can be connected to the output terminal.
- In terms of complying with standards, use copper wires that can operate at 75 C.
3.2 Mounting (Figure 2)
- PS-362 can be mounted on DIN rails which comply with EN50022 standards.
- Mount the device vertically. When mounting the device, it is recommended that the DC
output side stays on top side.
- Mind the device’s ventilation when mounting the device. After the mounting, it is
recommended to leave a 1 cm space between PS-362 and devices next to it.
