Three VAC Transformers Receive VDE Certification

VACUUMSCHMELZE (VAC) has announced that three of its Gate Drive transformers have received certification according to the IEC[1] 61558 standard. The transformers, which are documented in detail in the product information ‘Gate Drive Transformers for IGBT (PI-IA 1)’ are the first VAC transformers to receive VDE[2] certification. For VAC’s customers, obtaining certification for their devices incorporating these transformers will now be easier. VAC has also added the new 5032-X112 SMD transformer to its portfolio, also VDE-certified. The VDE certification reports can be supplied to customers on request.

The IEC 61558 standard applied in this certification is a general standard governing the “safety of power transformers, power supplies, reactors and similar products”.  As the standard does not specify particular applications, VAC’s customers can use the certified transformers with flexibility. In addition, all transformers manufactured by the Hanau-based company comply with its in-house UL1446 insulation system, VAC-ISO-F1. This makes it easier for customers to obtain UL[3] approval, which is typically a precondition of launching products into the US market.  

All three transformers feature low leakage inductance and high test voltages and comply with the requirements for reinforced insulation. In addition, they offer an extremely large voltage-time integral and are optimized for a range of operating frequencies.
