LED power supply 185W 36V 5.2A HLG-185H-36A

Professional LED power supply for demanding lighting applications

The HLG-185H-36A LED power supply is an advanced power solution for LED systems with a power of 185W, providing a stable output voltage of 36V at a current of 5.2A. The device belongs to the renowned HLG series from the manufacturer MEAN WELL - a global leader in the field of switching power supplies.

Construction and technical parameters

The power supply features a sealed metal enclosure with an IP65/IP67 protection class, enabling installation both indoors and outdoors. The Class I construction guarantees a high level of electrical safety.

The device operates in two modes simultaneously: constant voltage (CV) and constant current (CC), making it a universal solution for various LED configurations - from single diodes through strips and modules to large lighting panels.

Version A is equipped with internal potentiometers that allow for the adjustment of output parameters without the need to open the enclosure - the voltage can be adjusted in the range of 33~40V, and the current 2.6~5.2A. Adjustment is performed through special holes with rubber plugs.

The model achieves an impressive energy efficiency level of 93.5%, which translates to minimized thermal losses and lower operating costs. The built-in active PFC (Power Factor Correction) function ensures a power factor above 0.95 at full load, meeting the requirements of the latest energy standards.

The power supply operates within a wide range of input voltages (90_{305VAC / 127}431VDC) and frequencies (47~63Hz), allowing for use in various power systems worldwide.

Protection system and energy efficiency

The device is equipped with a multi-level protection system:

• Short circuit protection - automatic recovery after the fault is removed
• Overload protection - constant current limiting with auto-recovery
• Overvoltage protection - automatic shutdown at excessive output voltage
• Thermal protection - automatic shutdown upon enclosure overheating

Additionally, the device provides surge immunity up to 4kV according to the IEC61000-4-5 standard and meets EMC requirements for Class B.

The typical lifespan of the device exceeds 62 000 hours, and the standard warranty period is 5 years (manufacturer MEAN WELL). The device dimensions are a compact 228×68×38.8mm, and the weight is only 1.15kg.

Professional applications and operating conditions

Applications requiring high reliability:

• LED street lighting - IP67 weather resistance
• Industrial lighting for high warehouse halls
• Parking and garage systems
• Agricultural lighting (greenhouses, breeding facilities)
• Dynamic signage / animated displays

The device operates stably in an extreme temperature range from -40°C to +90°C, maintaining full power up to a case temperature of +60°C and reducing the load to 60% power at +70°C.

The power supply has full technical documentation and CE certificates, meeting the requirements of European safety standards for LED lighting equipment (EN61347).
