The MEAN WELL HLG-150H-36A and HLG-150H-48A are two LED driver options for 36V and 48V lighting loads. Both support constant-voltage and constant-current operation and use IP65 metal housings with fanless cooling. Their voltage, current and power ratings differ as shown below.
HLG-150H-36A and HLG-150H-48A comparison
| Parameter | HLG-150H-36A | HLG-150H-48A |
|---|---|---|
| Rated voltage | 36V | 48V |
| Rated current | 4.2A | 3.2A |
| Rated power | 151.2W | 153.6W |
| Constant-current region | 18–36V | 24–48V |
| Voltage adjustment | 33–40V | 43–53V |
| Current adjustment | 2.5–4.2A | 1.92–3.2A |
| Typical efficiency | 93.5% | 94% |
| Parameter | Specification |
|---|---|
| AC input | 90–305VAC, 47–63Hz |
| Ingress protection | IP65 (A type) |
| Control | Built-in voltage and current potentiometers |
| Dimensions (L × W × H) | 228 × 68 × 38.8mm |
| Working case temperature | −40 to +90°C; follow the output-load derating curves |
Specifications are taken from the 36V and 48V columns and A-type option of the linked HLG-150H datasheet. Check input-voltage and thermal derating for the actual installation.
Selecting a 36V or 48V driver
Match the load’s required voltage first, then confirm current and power. For constant-current operation, the LED string voltage must stay within the specified region. Built-in adjustment is intended for setting the chosen model; neither version should be selected solely by the HLG-150H series name.
Frequently asked questions
How do HLG-150H-36A and HLG-150H-48A differ?
The 36A model is rated at 36V, 4.2A and 151.2W. The 48A model is rated at 48V, 3.2A and 153.6W. Their voltage and current adjustment ranges also differ.
Does the A suffix include 3-in-1 dimming?
No. The A suffix identifies built-in voltage and current potentiometers. External 3-in-1 dimming is provided by other suffix versions in the series.
Is the HLG-150H-48A an IP67 power supply?
The HLG-150H-48A is IP65. The suffix-specific table should be used instead of applying the series’ IP65/IP67 description to every model.
