BSMJ Self-healing Shunt Capacitor

About the BSMJ Self-healing Shunt Capacitor

The BSMJ Self-healing Shunt Capacitor is part of the ELEHPD Capacitor range. 1.Small volume,light weight:lt is only 1/4and 1/5of the weight and volume of the outdated products respectively. 2.Low loss:With the actual loss less than 0.1,little radiation,low temperature rise,and good energy conservation effect. 3.Excellent self-healing performance:When a part of the isolation is fed through due to the overvoltage,it is capable of self-healing soas to continue the operation,therefore the reliability is improved greatly. 4.Safety:Equipped with self-discharging resistant and safty devices inside,the inner discharging resistant can make the attached electric discharged;when there is wrong with the capacitor,the fuse equipment can cut out the electric power,so that no more trouble with the capacitor,safty and reliable. 5.without oil leakage:this product adoped advanced half-solid soak materials driips melting point higher than 70℃,avoid leakage during operation and pritect the envirament,the capacitor will not no use since the leakage. ELEHPD manufactures and exports low voltage electrical products from Yueqing, Zhejiang, China, supplying distributors, panel builders, M&E contractors and OEM buyers worldwide.

Typical applications

Industrial control panels and PLC power rails
LED drivers, signage and display power
Battery charging and DC backup systems

Instrumentation and test equipment

How to specify the right Capacitor

Size the output current with at least 20-30 % headroom over the load
Check the input range covers the local supply, including brown-outs
Confirm the enclosure and cooling method for the panel temperature
Verify the protection set: over-current, over-voltage, thermal and short circuit

Frequently asked questions about the BSMJ Self-healing Shunt Capacitor

How much headroom should I leave on the power rating?

For continuous industrial duty plan on 20-30 % headroom above the measured load. For loads with high inrush, such as motors or capacitive input, allow more and check the surge rating rather than only the average current.

Do these units accept 110 V and 230 V mains?

Input ranges are model-specific and shown in the specification table. Where a wide-range input is available it is stated; otherwise send your mains voltage and we will match the model.

What protection features are built in?

Typical protection covers short circuit, over-current, over-voltage and thermal shutdown. The exact set is listed per model in the specification table above.

Can you supply matching DIN-rail or enclosed versions?

Open-frame, enclosed and DIN-rail variants exist across this family. Send the model you are working from and we will confirm the equivalent mounting option.
