印度采购需求：双色LED面板灯，LED照明，LED面板筒灯

I'm looking to source a single-phase power supply that operates within the range of 18W to 24W, with a current output of 300mA. The voltage requirements should be adjustable between 30V and 75V, and it's essential that the unit is isolated. I'm interested in discussing the specifications further, as well as the potential for bulk orders and pricing options. Could you please provide additional details on the available models that meet these criteria? Also, I'd appreciate information on lead times, warranty conditions, and any certifications that guarantee product quality and safety. Looking forward to your prompt response.
