**SVC**

“SVC” is a regen unit for short-term brake operation. The duty cycle is less than 50% (relating to 10 minutes). It corresponds to a large extent to the current series “RLD-B0”. The first number of the model code corresponds to the maximum electrical brake power of regen unit.

**SVC(S)**

“SVC(S) “is a regen unit for short-term brake operation with additional connecting terminals for an external passive harmonic filter “SKS-R”. The duty cycle is less than 50% (relating to 10 minutes). Apart from the connecting terminals for the filter, SVC(S) corresponds to a large extent to the current series “RLD-B0”. The first number of the model code corresponds to the maximum electrical brake power of the regen unit.

**SVCD(S) **

“SVCD(S) for VLT“ is a regen unit for continuous brake operation with additional connecting terminals for an external passive harmonic filter “SKS-R for VLT”. The duty cycle is 100%. This special variant is designed for use on a Danfoss VLT variable frequency drive. It corresponds to a large extent to the current series “RLD-D0“. The first number of the type code corresponds to the rated electrical power of the regen unit.

**DCV**

“DCV” is a power feed and feedback unit. It can supply one or more variable frequency drives via DC bus and feed surplus energy back into the network. It has a precharging circuit for the bus capacity of the variable frequency drives. “DCV” corresponds to a large extent to the current series „RFE-B3“. The first number of the model code corresponds to the rated electrical power of the power feed and feedback unit.

**DCoV **

“DCoV “ is a power feed and feedback unit. It can supply one or more variable frequency drives via DC bus and feed surplus energy back into the network. It has a precharging circuit for the bus capacity of the variable frequency drives. “DCoV “corresponds to a large extent to the current series „RFE-B2 “. The first number of the type code corresponds to the rated electrical power of the power feed and feedback unit.

**DCV(S) **

“DCV(S) “ is a power feed and feedback unit with additional connecting terminals for an external passive harmonic filter “SKS-D”. It can supply one or more variable frequency drives via DC bus and feed surplus energy back into the network. It has a precharging circuit for the bus capacity of the variable frequency drives. Apart from the terminals to connect the filter, DCV(S) corresponds to a large extent to the current series ”RFE-B3”. The first number of the type code corresponds to the rated electrical power of the power feed and feedback unit.

**DCoV(S) **

“DCoV(S)” is a power feed and feedback unit with additional connecting terminals for an external passive harmonic filter “SKS-D”. It can supply one or more variable frequency drives via DC bus and feed surplus energy back into the network. It has no precharging circuit for the bus capacity of the variable frequency drives. Apart from the terminals to connect the filter, the “DcoV(S)” corresponds to a large extent to the current series “RFE-B2”. The first number of the model code corresponds to the rated electrical power of the power feed and feedback unit.
