On the floor, UV curing falls apart the moment lamp power starts drifting. A 5% dip in spectral output can leave ink tacky at 300 m/min. Drop another 5% and you can stall the whole line. That’s why wholesalers and traders lean on our CE-certified constant current UV lamp power supply. It keeps irradiance steady across the lamp’s life, so you ship consistent work instead of chasing callbacks. What matters, technically We drive high-pressure mercury vapor lamps with closed-loop constant current control. That holds arc power stable, even as the lamp ages or the mains wobbles. The output stays regulated so peak irradiance at the cure plane stays within a tight band, preserving dose consistency for photoinitiator cross-linking. You get repeatable spectral output at the dominant 365 nm line, and controlled rise and ignition profiles that protect the quartz envelope. The unit supports 230 V and 400 V systems, with industrial connectors and clear wiring for quick integration. Why it holds up in real production On high-volume offset, flexo, and screen lines, curing energy density has to stay in spec from the first sheet to the last lamp cycle. This supply keeps lamp current stable and spectral output repeatable, so your cure window stays wide enough to handle ink lot variation and substrate changes. The payoff is fewer rejects, stable throughput, and predictable lamp replacement planning. CE certification also simplifies compliance for global resale, cutting down approval overhead for wholesalers. A few shop-floor reminders Match the power supply to your lamp’s rated current and ignition type. Check reflector alignment and cooling — if things run hot, output compresses and lamp life gets cut short. Plan for EMI suppression and solid grounding. For the cleanest setup, monitor dose at the substrate with a spectral radiometer and log irradiance versus line speed. That’s how you lock in the process window for real.
