When is a backup power supply required for interface protections?

Whenever the interface protection is installed as independent device from the photovoltaic inverter, the standards require an auxiliary power supply which supports the interface protection (IP), the interface switch (IS) and a possible back-up device in the event of a power failure. _____________________________________________________________________ Other information on this topic Visit the website page dedicated to Backup [...]

How long does it take to recharge PMVFUPS01?

A maximum time of 15s is required to fully charge the storage capacitors. The output voltage is present only when the charge is completed. It must be considered that the recharge is required at the very first switch on as well. _____________________________________________________________________ Other information on this topic Visit the website page dedicated to Backup power [...]

How to choose the interface and back-up switches to be coupled to PMVFUPS01?

PMVFUPS01 accumulates enough energy (200Ws) to correctly drive PMVF series interface protection, a BF or B series contactor by LOVATO Electric acting as an interface switch and the shunt release of the backup. The selection of the right contactor according to the AC3 power is suggested on PMVFUPS01 user’s manual. In case of third party [...]
