Features
• Compatible with TRIAC (forward-phase or leading-edge),
ELV (reverse-phase or trailing-edge) and 0-10 V dimmers
• ESSxxxW: TRIAC and ELV dimming only at 120 Vac.
• ESSxxxE: TRIAC and ELV dimming only at 230 Vac.
• Linear 0-10 V dimming transfer function: 10V=100%, 1V=10%, 0.1V=1%. Models
with the “Z1” suffix exhibit a non-linear 0-10V dimming profile(10V to 9.1V=100%,
1V to 0.8V=1%, <0.8V dim-to-off).
• Lifetime: 50,000 hours at 70°C case temperature
• Protections: output open load, over-current and short-circuit (hiccup), and
over-temperature with auto recovery
• Conducted and radiated EMI: Compliant with FCC CFR Title 47 Part 15 Class B
(120 Vac)/Class A (277 Vac) and EN55015 (CISPR 15) at 220 to 240 Vac
• Complies with ENERGY STAR® luminaire specification and with
DLC (Design Light Consortium®) technical requirements
• IP64-rated case with silicone-based potting. IP66 for ESST040.
• 90°C maximum case temperature
