Checking a new or replacement supply
Verify the required output voltage, total load current and mounting space before ordering. The 24V version has its own output rating, which should be used instead of the generic series power class.
Keep ventilation openings unobstructed. When installing inside a warm cabinet, use the datasheet derating curve to determine the available load. The PDF below includes the terminal and mechanical drawings for checking a replacement.
Frequently asked questions
What is the output current of the LRS-100-24?
Its rated output current is 4.5A at 24V DC, with 108W rated power.
Can it accept 115VAC and 230VAC input?
Both are within its specified full-range 85–264VAC input. Use the datasheet input and derating conditions when planning the installation.
What size is the LRS-100-24?
The enclosure measures 129 × 97 × 30mm in length × width × height. Check the PDF drawing for mounting-hole positions.
Does it have an internal cooling fan?
No. It uses free-air convection and needs ventilation in the final equipment.
