FUSE
LINKS FOR PHOTOVOLTAIC INSTALLATIONS
DF ELECTRIC launch a new photovoltaic modular fuse
holder and fuse Pv for photovoltaic applications.
The first feature that this news products off ers, is the assigned
voltages, in one hand the fuse holder with 1000 V DC and in the other
hand the fuse with 900 V DC. They have been developed
to off er 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 900V DC.
The fuses can be also used meet the requirements for instruments (multimeters)
and traction equipment auxiliary circuits |

HIGH
SPEED FUSES FOR SEMICONDUCTOR PROTECTION RAPIDPLUS aR-gR
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 specfi c 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 rectiÍ ers, UPS, converters,
motor drives (AC and DC), soft starters, solid state relays, photovoltaic
inverters, welding inverters and any application where it i necessary
to protect semiconductor devices. |
