Class II Power Supplies Drive LED Lighting/Signage Designs June 27, 2008
Designed for outdoor LED lighting and sign applications, the LED-240 series switching power supplies deliver 240W of output power and come in 4.84" x 6.54" x 2.22" aluminum enclosures with an IP65 rating. The supplies provide four isolated and independently regulated 12-Vdc outputs, rated at 5A each with UL1310/1585 approvals. Four 60W outputs meet NEC Class II safety requirements and the units employ zero voltage switching with four independent synchronous buck regulators to reduce low frequency noise, improve transient response, and increase efficiencies. Other features include a universal ac input, active PFC for EN6100-3-2 compliance, and efficiencies greater than 85%. Pricing starts at $150 each/1,000. DONGAH ELECOMM USA, Richardson TX.
