Engineering FAQ

Frequently Asked Questions

What international safety and EMC standards do Premium PSU DIN rail supplies comply with?
All Premium PSU DIN Rail devices are designed and certified to international safety standards including IEC/EN 62368-1 (Audio/video, information and communication technology equipment) and IEC/EN 61010-1 (Electrical equipment for measurement, control, and laboratory use). Electromagnetic compatibility is tested against IEC/EN 61000-6-2 (Immunity for industrial environments) and IEC/EN 61000-6-3 (Emission standard for residential, commercial and light-industrial environments).
How does the tool-less push-in connection system benefit control cabinet wiring?
Our DIN rail devices feature dual paired input and output push-in terminal connectors. This enables fast, tool-less wire insertion, eliminates screw loosening caused by shock and vibration, and allows easy daisy-chaining across multiple modules in control cabinets without extra distribution blocks.
Can Premium PSU DIN rail supplies be connected in parallel for redundancy?
Yes. Standard models like the DPS-240 incorporate an integrated active ORing decoupling circuit for direct parallel N+1 connection. For non-ORing supplies or system-level decoupling, our RDM-40 redundancy module decouples two power supply outputs up to 40 A total current.
Does Premium PSU manufacture custom DIN rail power supplies for OEM projects?
Yes. Supported by 40+ years of power conversion expertise, our engineering department in Barcelona can adapt electrical specifications, conformal coatings, mechanical housings, or communication options for your volume OEM requirements.
