Constant Current LED Drivers
PSB Series
15–50 W Programmable Constant Current LED Driver With Tri-Mode Dimming
| Input Voltage | Max Output Power | Efficiency | THD | Max Case Temp | Power Factor | Dimming Method | Dimming Range | Start Time |
|---|---|---|---|---|---|---|---|---|
| 120 & 277 Vac, 220 to 240 Vac | 50 W | Up to 90% | < 20% | 90 °C (measured at the hot spot) | > 0.9 | Forward-Phase, Reverse-Phase & 0–10 V | 1–100% (% of Iout) | 300 ms |
Features:
- Meets IEEE 1789-2015 “no impact” recommended practices for flicker (0–10 V dimming)
- Non-linear 0–10 V dimming profile with dim-to-off pre-loaded by default (10 V to 9.0 V = 100%, 1.5 V to 0.7 V = 1%, < 0.7 V = dim-to-off)
- UL8750 Class P, Class 2 power supply
- Lifetime: 50,000 hours @ Tc ≤ 75 ℃
- 90 ℃ maximum case hot spot temperature
- IP20-rated case with silicone-based potting
- No TRIAC/ELV dimming for PSBxxE models; only 0–10 V without dim-to-off dimming
- Complies with ENERGY STAR®, DLC (DesignLight Consortium®), CA Title 24, and NEMA SSL-1-2016 technical requirements
- Additional safety approvals when using the optional strain reliefs for models with “-T” suffix
Programming:
- Serial port programming
- Current: 100% to 50% in each voltage range
- Data log read: SKU, S/N, lot code, hours of operation, FW rev.
- Fully programmable and selectable 0–10 V dimming profiles: Non-Linear with dim-to-off, Logarithmic, Non-Linear without dim-to-off
Applications:
- Architectural
- Commercial lighting
- Indoor lighting
- Residential lighting
