252

The LMxx-23Bxx series of enclosed power supply launched by MORNSUN, in addition to meeting the normal operating conditions, also can be used in applications with higher requirements for input voltage, temperature, humidity, altitude, and electromagnetic interference in a long term. The input voltage range is as wide as 85-305VAC, and the power range covers 15-150W. The only 25mm height is more superior than industry level. At the same time, it has the advantages of isolation voltage as high as 4000VAC, no-load power as low as 0.5W, and efficiency as high as 88%. It adopts double Y design, and meets IEC/EN/UL62368/CCC certification standards.

Main Working Conditions

A: Voltage Fluctuation

The input voltage range is 85-305VAC/100-430VDC, which solves the three major shortcomings of conventional 85-264VAC input products: LM-23B

  1. The universal input voltage of 85-305VAC covers the standard voltage of 110/220/277VAC.
  2. It solves the power failure caused by voltage fluctuations in grid power distribution or generator.
  3. It can also work normally under the transient high input voltage (the input voltage exceeds 264VAC when the device is turned off).

B: High Altitude

It meets the 5000m altitude application, and the product has passed high/low temperature altitude test, long-term aging test, etc.

C: EMI

  1. EMI meets CISPR32/EN55032 CLASS B reducing harm to the human body and interference to other equipment.
  2. Surge immunity is up to 4KV, strong anti-interference ability is suitable for harsh environment applications.

D: High/Low Temperature

Wide operating temperature range is -30℃ to +70℃. The product can still work at full load and has a strong start-up ability while at low temperature of -30℃. When it is running at 70℃, the temperature rise of product components is low and the service life is long.

In order to meet the diversified applications, MORNSUN has simultaneously launched extended models:

LMxx-23Bxx-Q:  It has three-proof paint process, and features excellent insulation, multiple resistance of moisture, leakage, vibration, dust, corrosion, aging, corona and other properties, which is suitable for harsh industrial environments.

LMxx-23Bxx-C: It has terminal cover that can prevent the human to touching the terminal by mistake.

Applications It can be widely used in industrial control, LED, street light control, electricity, security, telecommunications, smart home, etc. And it is suitable for those applications with high requirement of dimensions and EMI.

Features

  1. Universal input voltage: 85 – 305VAC/100 – 430VDC
  2. Accepts AC or DC input (dual-use of same terminal)
  3. Operating temperature range: -30℃ to +70℃
  4. Efficiency up to 88%
  5. Low standby power consumption: < 0.5W
  6. I/O isolation voltage: 4000VAC
  7. Output short circuit, over-current, over-voltage protections
  8. Safety according to IEC/EN/UL62368 (Pending)
  9. Withstand 335VAC surge input for 5s
  10. Over-voltage class Ⅲ (designed to meet EN61558)
  11. Operating altitude up to 5000m
