Data sheet

UNO POWER power supply unit - for NEC Class 2

applications

The UNO POWER power supply unit impresses in world-

wide use thanks to maximum energy efficiency. Low no-

load losses and the high degree of efficiency save energy.

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

– Maximum energy efficiency thanks to optimized effi-

ciency over the entire operating range of the power sup-

ply unit and low no-load losses

– Particularly compact: 90W of power from this narrow

power supply, which is just 55mm wide

– Output power limited < 100W according to UL1310 for

NEC Class 2 applications

A Figure 3 7.4 B 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 qualified specialist personnel may install, start up, and operate the device. Observe the national safety and accident prevention regulations. 8.2 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/ 90W/C2LPS 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] In the event of overload (I > IN), the device reduces its output voltage. If the output voltage is greater than UN x 0.9, the green DC OK LED lights up. If the output voltage drops below UN x 0.5, the device shuts down. After a short time, the device attempts to start up again.

UNO-PS/1AC/24DC/ 90W/C2LPS 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.
