Switching Power Supply 1PS (150W)
|
These power supplies are designed for general-purpose use to power electrical and electronic devices with DC voltage in indoor environments without explosive hazards. The .xP version models can be connected in parallel to achieve a higher output current. If the customer requires a higher output voltage, the .xD version models can be connected in series. The output voltage can be set within the range of 5 V to 48 V.
The nominal output voltages and their respective maximum output currents are listed in the table. The power supply is protected against output short-circuits. Mains connection is established via a FLEXO power cord or a WAGO connector. The unit can be supplied with either a FAST-ON or a WAGO output connector.

Description of Additional Functions:
Battery Disconnect Switch
The battery disconnect serves to protect the accumulator. When a device is powered by a battery, the battery discharges, causing the terminal voltage to drop. When the voltage falls to 10.5 (or 21V for a 24V battery), the disconnect galvanically isolates the battery from the load. This prevents further discharge. If disconnection does not occur, the battery could discharge to 0 V, which may lead to permanent battery damage.
Optional Versions and Functions:
Some basic versions designated by the first character after the decimal point can be extended with additional functions and features. These are specified by the second character after the dot. Supplementary designs should be consulted with the manufacturer.
.x2 - Mains failure signaling (relay contact)
.x8 - Input Power 110 V AC
.x9 - Version with enhanced climatic and mechanical resistance
.xT - Operating temperature from -20 °C
.xD - Version for series connection of power supplies
.xP version - Version for parallel connection of power supplies
.xM - Version for Emergency Lighting in Apartment Buildings
.xxSS - Designed for 19″ rack mounting
.x2T - Operation indication via relay contact, designed for temperatures from -20°C
Note on the .xP version: Parallel connection is only possible for power supplies in the .xP version, provided that the minimum load is at least 20% of the nominal current of all connected units. Power supplies in the .xP version have an output voltage stability of 2%.
There are special versions of the 1PS power supplies. These are designated by letters following one or two characters that represent the basic and, if applicable, supplementary designs.
Parallel connection of the battery to the stabilized power supply output:
The simplest 12 V (24 V) backup system can be created using a 13.8 V (27.6 V) stabilized power supply and a 12 V (24 V) battery connected in parallel to the supply output. Such a system is capable of briefly delivering a higher current than the maximum rated current of the stabilized power supply.
Optional Accessories:
DIN rail mounting bracket for 1PS power supplies.
19″ rack mounting kit.
