The SITOP PSU3400 6EP3133-0TA10-0AY0 is a slim DC/DC converter that bridges the gap between 12V DC sources and 24V industrial loads. At just 32mm wide, it fits into the kind of space-constrained enclosures common in mobile machinery, remote telemetry cabinets, and battery-backed monitoring stations — environments where a 12V supply is native (vehicle alternator, lead-acid battery bank, solar charge controller) but the automation hardware expects 24V.

Stable Output from a Fluctuating Input

The converter accepts any DC input from 9 to 18V — covering the full operating range of a 12V nominal battery from deep discharge through alternator charge voltage — and delivers a regulated, adjustable 24VDC output at up to 4A continuous. Galvanic isolation between input and output (SELV, 24VDC side) means noise, ground loops, and transient voltage spikes on the source side do not propagate to the load. Reverse polarity protection on the input prevents damage from wiring errors during installation.

Industrial and Marine Ready

DNV GL and ABS marine approvals qualify the module for shipboard use, where 12V DC distribution is common in smaller vessels. The 32 × 100 × 100 mm housing mounts on standard 35mm DIN rail with screw terminals for all connections. An adjustable output voltage potentiometer allows compensation for voltage drop over long cable runs to the load. A signaling contact integrates the converter into the plant monitoring system for "output OK" status.

Key Decision Parameters

For 48VDC input applications, the PSU3400 series also includes the 6EP3233-0TA10-0AY0 (48V→24V, 3.5A). For universal AC/DC input in the same product family, see the PSU3400 uni variants.
