Description

The Siemens 6EP1434-2BA20 is a stabilized DIN rail power supply in the SITOP PSU300S series, designed to convert a three-phase 400–500 V AC input into a regulated 24 V DC output. It delivers a rated 10 A — extendable to 12 A at ambient temperatures up to 45°C — and supports parallel operation of two units for increased capacity.

It snaps onto a standard 35 mm DIN rail with screw-type terminal connections at input and output. The enclosure carries an IP20 rating and operates across −25 to +70°C via natural convection cooling. Output voltage is adjustable from 24 to 28 V via the onboard potentiometer, and a relay contact signals DC OK status during normal operation.

Frequently Asked Questions

What input supply does the 6EP1434-2BA20 require?

It requires a 3-phase AC supply rated 400–500 V, with an operating range of 340–550 V to accommodate line fluctuations.

Can the 6EP1434-2BA20 output more than 10 A when needed?

Yes — output extends to 12 A at ambient temperatures up to +45°C, and the unit supports 150% overload for up to 5 seconds per minute.

Is the 6EP1434-2BA20 approved for use in hazardous or marine environments?

Hazardous location (ATEX, IECEx, NEC Class 2) approvals are not available. Marine use is certified by ABS and DNV GL.
