electric shock in place. Incorrect connection may create dangerous result for people and environment.
Incorrect connection may result in permanent damage to the performance of the device.
- Before you energize the device or remove the device from mains, make sure that the supply cable isn’t
connected to mains.
- Supply input of the device must be connected according to EN60950 standards.
! A supply voltage greater than 265V AC may result in an explosion in the device or in damages to the user.
- Device supply must be at a sucient power capacity and must comply with security standards.
-
Cables connected to the outputs of PS-722 must be suitable for the maximum current that PS-722 can provide.
- After device connection is nished, connection points must be protected against accidental contacts.
- Mounting of the device must be done vertically as shown in Figure-1.

1.3 Operation : The part of the device which is numbered as 1 in Figure-1 is the input voltage connection
point of PS-722 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-722 and its polarity is shown with + and - on the device body. PS-722 supplies adjustable DC voltage
from these connection points. When supply voltage is applied to PS-722, the LED which is numbered as 4
in Figure-1 will light up. When this is LED is lit, it indicates that PS-722 is working and it generates an output
voltage. The part of the device which is numbered as 3 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. (In case of thermal protection power on reset is needed).

- 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 can operate up to an ambient temperature of +55⁰C.*
PS-722 has LED indicator (Parts 4 in Figure-1).
- When there’s no energy : Output OK LED is o.
- Normal operation mode : Output OK LED is on.
- Short circuit : Output OK LED is 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 LED turn o. The device
makes blinks. When the load condition returns to normal, the device starts to opening again.
- Overheating + Overload : 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-722 draws maximum 1.7A AC and minimum 0.8A AC. Wire thickness
must be selected according to these values. Maximum 14 AWG stranded wire (2.5 mm2) or 12 AWG solid wire
(4 mm2) can be connected to the input terminal.
- DC output (2): Output current is 3A DC. Wire thickness must be selected according to this value. Maximum
14 AWG stranded wire (2.5 mm2) or 12 AWG solid wire (4 mm2) can be connected to the output terminal.
- In terms of complying with standards, use copper wires that can operate at 75oC.
