Power supply modules

■Overview

PS 405 and PS 407 load power supplies

The modules of the AS 488/TM automation system are provided with the DC 5 V and DC 24 V operating voltages from the PS 405 and PS 407 power supply modules via the backplane bus.

A PS 407 power supply module (for AC 120/230 V; only for oper- ation without TELEPERM M I/O modules) or a PS 405 power sup- ply module (for DC 24 V) is required depending on the input volt- age.

The power supply module is inserted on the left in the rack. It is fitted in a casing and is cooled by natural convection. The front of the module contains:

•LEDs for display of correct output voltages, correct backup battery voltage and internal faults

•Button for acknowledgment of faults

•On/off switch for output voltages

•Battery compartment (hidden) for backup battery

•Switch (hidden) for activation of battery monitoring

•Mains voltage selector (hidden) for AC 120/230 V

•Mains connection (hidden) with 3-pin plug.

The DC 24 V load power supplies are each available in 10-A and 20-A versions. The 20-A version is only required in conjunction with TELEPERM M I/O modules.

The AC 120/230 V load power supply must not be used together with TELEPERM M I/O modules.

Backup battery

A backup battery is additionally required for the AS 488/TM au- tomation system. The PS 405 and PS 407 load power supplies are fitted with a battery compartment. If the power supply fails, the time and date in the CPU are buffered.
