Constant Current LED Drivers
ESP/ESPT Series
40 to 60 W, Tri-Mode Dimming™ (0–10 V & TRIAC/ELV)
| Input Voltage | Max Output Power | Output Voltage | Output Current Range | Efficiency | THD | Max Case Temp | Power Factor | Dimming Method | Dimming Range | Start Time |
|---|---|---|---|---|---|---|---|---|---|---|
| 120 to 277 Vac | 60 W | 24 to 56 Vdc | 700 mA to 1.4 A Constant Current | up to 87% | < 20% | 90º C (measured at the hot spot) | >0.9 | Forward-Phase, Reverse-Phase & 0-10 V | 1-100% (% of Iout) | 400 ms |
Features:
-
ESPT has the same features as the ESP series, but with a thermally-enhanced plastic case
- Compatible with TRIAC (forward-phase or leading-edge), ELV (reverse-phase or trailing-edge) and 0–10 V dimmers
-
ESPTxxxW models: TRIAC and ELV dimming only at 120 Vac
- 90°C maximum case hot spot temperature
- Class 2 power supply
- Lifetime: 50,000 hours at 70°C case hot spot temperature. (Some models have higher lifetime. Check lifetime curves on page 6 of data sheets.)
- IP66-rated case with silicone-based potting
- Two 0–10 V dimming profiles are available:
- Linear 0–10 V dimming: 10 V = 100%, 1 V = 10%, 0.1 V = 1%
- Non-linear 0–10 V dimming: 10 V to 8.1 V = 100%, 1 V to 0.8 V = 1%, < 0.8 V dim-to-off
- 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) and Class A (277 Vac), and EN55015 (CISPR 15) at 220, 230, and 240 Vac
- Complies with ENERGY STAR®, DLC (DesignLight Consortium®) and CA Title 24 technical requirements
- Worldwide safety approvals
Applications:
- Architectural
- Commercial lighting
- Downlight
- Indoor lighting
- Outdoor LED Light
- Residential light

Notes:
-
ESPT models with the “-Z1” suffix exhibit a non-linear 0–10 V dimming profile with dim-to-off: 10 V to 8.1 V = 100%, 1 V to 0.8 V = 1%, < 0.8 V dim-to-off
-
The ESP/ESPT driver case must be mounted by using a minimum of two metal clips. By default, the ESP/ESPT driver is shipped with 2 metal clips. Additional metal clips can be ordered with the following part numbers:
- ESPT-CLIPS-100: bag of 100 clips
- ESPT-CLIPS-1k: bag of 1000 clips
