ESSV040W-1400-27 Description

Short technical summary and product information.

The ESSV040W-1400-27 is a constant current LED driver from ERP Power's ESSV series, delivering 38W at 1.4A with an output voltage range of 20-27VDC. It operates from a nominal input voltage of 120 to 277VAC and achieves up to 87% typical efficiency. The driver supports Tri-Mode dimming, compatible with 0-10V analog, TRIAC (forward-phase), and ELV (reverse-phase) dimmers, with a dimming range of 1% to 100% of output current.

Designed for commercial and residential lighting applications, the driver includes protections against over-current, over-temperature, short-circuit, and output open load. It features a power factor >0.9 and total harmonic distortion <20%. The unit is ENERGY STAR, DLC, and CA Title 24 compliant, with EMI compliance to FCC Part 15 Class B (120VAC) / Class A (277VAC) and EN55015.

The driver is housed in an IP66-rated plastic case with silicone potting, measuring approximately 84.7 x 40.7 x 27.3 mm (datasheet dimensions). It is chassis mountable with wire lead terminations. The maximum case temperature is 90°C, and the minimum lifetime is 50,000 hours at 70°C case temperature. The driver carries UL Class P and 5VA flammability rating.
