Choose a repair type, check the important specifications, and go directly to the right IRENEX catalogue section.
Clear guidance first. Relevant products second.
Start at the DC bus, then inspect switching-stage capacitors, relays, BMS and DC-DC control modules.
Use dependable 105°C electrolytics for hot switching supplies and safety-rated film capacitors across mains circuits.
Choose an enclosed supply with the correct output voltage and enough current capacity for cameras, access control and auxiliary devices.
Confirm control voltage, relay pin format and contact load before replacing panel components.
For control boards and domestic equipment, begin with visibly damaged electrolytics, safety capacitors and switching relays.
Build a teaching bench or repair stock with capacitor assortments, modules and task-focused kits.
These checks prevent the most common replacement mistakes.
Match capacitance, use the same or a higher voltage rating, confirm polarity and physical dimensions, then choose the correct temperature and ESR duty.
Common requirements include high-voltage DC-bus electrolytics, low-ESR capacitors in switching sections and film capacitors for filtering or suppression.
Send the markings, board reference, specification or a clear photo to our component expert. Rare and obsolete components can also be sourced.
Share the SKU, specification or board photo with the IRENEX component expert.
