About this product

KING rainproof LED power supplies are built for signage that lives outdoors. The MIJI-400 is a constant voltage 12V driver rated at 400W, housed in a sealed IP53 case that shrugs off rain splash, dust and the humidity of a coastal Indian summer.

What makes it suited to Indian sites:

– Wide input range: AC 187 to 260V at 50/60Hz, so it keeps regulating through the voltage swings and brownouts common on local single phase supply

– Full 400W continuous output at DC 12V plus or minus 5%, delivering 33.3A for long runs of LED modules

– IP53 sealed housing with a vented, powder coated shell that sheds water while still dissipating heat

– Triple protection circuitry covering overvoltage, overcurrent and short circuit, so a wiring fault at the sign end does not take the driver with it

– SELV rated output, which keeps the low voltage side safe to work on during installation and servicing

– Rated to TC 85 degrees C at the case and TA 50 degrees C ambient, giving real headroom inside a sealed sign box under direct sun

The unit carries CE and RoHS marking, is manufactured under ISO9001:2008, and is BIS registered for sale in India. Terminals are clearly labelled: L, N and FG on the AC input side, and paired V minus and V plus on the DC output side, which makes for quick, unambiguous site wiring.

Genuine Overseas stocks KING drivers alongside G-TECH and Meanwell so fabricators can match the driver to the job and the budget. Call or send a WhatsApp message for current wholesale pricing and availability.
