Primary-switched power supply unit

UNO-PS/1AC/24DC/240W

Data sheet

The UNO POWER power supply makes a worldwide im-

pression thanks to maximum energy efficiency. Low idling

losses (No Load) and the high degree of efficiency save en-

ergy.

Thanks to its high power density, the UNO POWER power

supply unit is the ideal solution, particularly in compact con-

trol boxes.

Features

– Worldwide use thanks to input voltage range of

85 VAC ... 264 VAC

– Superior system availability through reliable power sup-

ply with 24 VDC ... 28VDC

– Maximum energy efficiency thanks to optimized effi-

ciency over the entire operating range of the power sup-

ply unit and low idling losses

– Particularly compact: 240W of power from this narrow

power supply, which is just 45mm wide

– Reliable supply thanks to the high MTBF (Mean Time

Between Failure) greater than 500 000 h (40°C)

– High operating range from -25 °C to 70 °C

– Idle and short-circuit-proof

UNO-PS/1AC/24DC/240W 7.3 Mounting on a DIN rail The power supply unit can be installed on all 35 mm DIN rails according to EN 60715. A B Figure 6 7.4 Mounting on a DIN rail Normal mounting position When installed, the input terminal blocks must be at the bottom and the output terminal blocks at the top. If the power supply unit is installed in a mounting position other than the normal mounting position, the output power must be reduced.

Only professionals may install, start up, and operate the device. Observe the national safety and accident prevention regulations. 8.2 Mains connection The device can be connected to single-phase AC or threephase power grids (TN-S, TN-C, TT, and IT) while considering the nominal input voltage.

UNO-PS/1AC/24DC/240W 9 Operating behavior of the power supply unit 9.1 Normal operation In normal operation, the loads are supplied with a constant output voltage of 24 V DC. 9.2 Overload response [V] The power supply operates according to the characteristic curve shown in the figure. In the event of an overload (I > IN), the device reduces the output voltage. If the output voltage drops below UN x 0.8, the output current is also reduced.
PAGE 14
UNO-PS/1AC/24DC/240W 9.4 Behavior in the case of alternative mounting positions For mounting positions that differ from the normal mounting position, the output power must be reduced (position-dependent derating). The characteristic curve can be used to determine the maximum output power to be drawn for each ambient temperature for different mounting positions.

UNO-PS/1AC/24DC/240W 10.2 Operating power supply units in parallel Power supply units of the same type can be connected in parallel to increase both redundancy and power. To ensure symmetrical current distribution, all cable connections from the power supply unit to the busbar must be the same length and have the same conductor cross section. Redundant operation Redundant circuits are suitable for supplying systems which place particularly high demands on operational safety.
