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 [...]

In photovoltaic applications, where are contactors installed?

In the construction of photovoltaic systems, international standards and national rules must be kept in mind. The national rules may have significant variations between different nations. However, the contactors in photovoltaic applications are typically installed immediately upstream and downstream of the inverter. The contactor on the AC side is a common contactor that must be [...]

Can BFD contactors be used for applications other than photovoltaics?

BFD contactors are contactors specifically designed to interrupt DC loads. They find their major use in the photovoltaic applications, but are also suitable for any DC application such as railway traction, batteries control, telecommunication systems, DC drivers etc. _________________________________________________________________________________ Other information on this topic Visit the website page dedicated to contactors.
