Handler Implementation Notes

Pattern Matching

Mean Well patterns use the format:

code
^SERIES-[0-9]+(?:[A-Z])?(?:-[0-9]+)?(?:[A-Z]+)?$

The handler uses explicit series matching for reliability.

Package Code Extraction

Returns wattage with "W" suffix:

java
handler.extractPackageCode("RS-25-5")  // Returns "25W"
handler.extractPackageCode("LRS-350-24")  // Returns "350W"

Output Voltage Extraction

Extracts voltage after second hyphen:

java
handler.extractOutputVoltage("RS-25-5")  // Returns "5V"
handler.extractOutputVoltage("HLG-150H-24A")  // Returns "24V"

Series Extraction

Returns the series prefix:

java
handler.extractSeries("RS-25-5")  // Returns "RS"
handler.extractSeries("HLG-150H-24A")  // Returns "HLG"

Supported ComponentTypes

java
ComponentType.POWER_SUPPLY
ComponentType.POWER_SUPPLY_AC_DC
ComponentType.POWER_SUPPLY_DC_DC
ComponentType.POWER_SUPPLY_MEANWELL
ComponentType.POWER_SUPPLY_AC_DC_MEANWELL
ComponentType.POWER_SUPPLY_DC_DC_MEANWELL
ComponentType.LED_DRIVER
ComponentType.LED_DRIVER_MEANWELL

Replacement Rules

Two Mean Well parts are considered replacements if:

  1. •Same series (e.g., both RS)
  2. •Same output voltage
  3. •Replacement has equal or greater wattage

Example: RS-50-5 can replace RS-25-5 (same series, same voltage, higher wattage)

Helper Methods

The handler provides additional utility methods:

java
// Check if LED driver
handler.isLEDDriver("HLG-150H-24A")  // true
handler.isLEDDriver("RS-25-5")  // false

// Check if DIN rail
handler.isDINRail("HDR-30-24")  // true
handler.isDINRail("RS-25-5")  // false

// Check if DC-DC converter
handler.isDCDC("SD-25C-12")  // true
handler.isDCDC("RS-25-5")  // false

// Get product description
handler.getProductType("RS-25-5")  // "Economy Enclosed Switching Power Supply"
handler.getProductType("HLG-150H-24A")  // "LED Driver with Dimming"

Learnings & Edge Cases

  • •HLG series has optional "H" suffix for high efficiency models before voltage
  • •LED drivers with dimming have letter suffix (A, B, AB, D, DA)
  • •DC-DC converters use letter codes for input voltage range (A, B, C, D, G, L)
  • •Some series have identical wattage/voltage with different features (e.g., RS vs NES)
  • •DIN rail width is not encoded in MPN, must reference datasheet
  • •IP rating for LED drivers varies by series (LPV=IP67, HLG=IP65/67)
