Supply bottlenecks for 24 VDC switching power supplies?

Due to the corona pandemic and cross-border logistics problems, the procurement of primary switched-mode power supplies can become increasingly difficult and expensive.

Should it become apparent in the coming weeks that the delivery of your controller is blocked due to the lack of switching power supplies, a conventional transformer power supply might be the right way to solve the acute procurement problem quickly and easily.

From our warehouse and with speed delivery service*, we supply you with power supplies from one day to the next.
Single-phase power supplies: EGSU, EGSUM, EGSUA
Three-phase power supplies: DTG, DTGS

Thanks to our 24-hour service** we can produce and deliver custom-made articles within a very short time.

*Delivery area Germany; provided that parcel services can exercise their standard and express services without restrictions.

**applies to individual items and urgent requirements within 24h.
