Interface and Power Details
The VE5135 accepts two DC inputs through screw terminals and steers power to a single output rail. Steering diodes isolate the sources and prevent reverse current between supplies. Therefore, technicians gain seamless failover without manual switching or downtime. The module mounts on a standard DIN rail and needs no special tools.
Physical and Environmental Parameters
The unit measures roughly 125 mm by 90 mm by 60 mm and weighs about 0.45 kg. Its compact housing fits tight enclosures and keeps panel layout efficient. Meanwhile, the -40°C to 70°C operating range suits remote and outdoor installations. The on-board energy storage holds the output steady during brief input interruptions.
Why This Module Matters
Plant teams value the VE5135 for its seamless redundancy and rugged temperature range. The capacitor bank bridges short supply gaps during source switching. As a result, connected equipment avoids resets and keeps running without interruption. Technicians also appreciate the clear terminal labeling and quick DIN rail mounting.
