DF ELECTRIC launch a
new photovoltaic modular fuse holder and fuse Pv for photovoltaic
applications.
The first feature that this news products offers, is the assigned
voltages, in one hand the fuse holder with 1000 V DC and in
the other hand the fuse with 1000 V DC. They have been developed
to offer a compact, safety and economic protection solution
in photovoltaic installations where due to the increase of the
power and technologic evolution, no-load voltages up to 1000V
DC.
The fuses can be also used meet the requirements for instruments
(multimeters) and traction equipment auxiliary circuits. |

Semiconductors are electronic components
extremely sensible to overloads and short-circuit, therefore
they cannot be protected with general purpose fuse-links. For
this reason there are ultra rapid fuse-links for this specific
purpose, with very fast melting characteristics, low let-through
energy values (I2t) and adequate selective coordination with
protection devices upstream.
Typical application comprise protection of semiconductors (diodes,
thyristors, triacs, etc) used in power rectifiers, UPS, converters,
motor drives (AC and DC), soft starters, solid state relays,
photovoltaic inverters, welding inverters and any application
where it is necessary to protect semiconductor devices.
