About this product
Meanwell is universally recognised as the gold standard in LED power supplies for professional lighting and signage applications worldwide. The ERPF-400-12 lives up to this reputation with a specification that leaves nothing to chance.
Key technical features:
– Output: 400W at 12V DC
– Input: Universal AC 100-240V (covers all Indian single-phase supply variations)
– Efficiency: Up to 91% — substantially higher than budget alternatives, meaning less heat generated inside sign boxes and lower electricity bills for the end-client

– Designed against rain splash — suitable for installation in open-back sign enclosures exposed to driven rain
– 100% full-load burn-in tested at the factory before dispatch — every single unit is tested, not just a sample batch
– Protection suite: Short circuit / overload / over voltage — comprehensive protection for the LED modules connected downstream
– Warranty: 3 years
