Furse ESP D1 Series Enhanced Mains Power Protectors
|
Following in the footsteps of our market-leading M1 Series of mains
power surge protectors, the new D1 Series now offers industry leading low
let-through voltage combined with the convenience of mounting to a
standard 35mm DIN rail.
With a choice of LED or innovative LCD display, and opportunity for remote
mounting, D1 protectors establish a new benchmark for professional surge
protection devices within the electrical marketplace.
Enhanced protection to BS EN 62305 - Enhanced protection further minimises
the risk of dangerous sparking (leading
to flashover and electric shock hazards)
as well as equipment damage, compared
to standard protection.
Repeat protection in lightning intense environments -
Protectors offer repeated protection
against transient overvoltages, with a
5 year warranty.
Compact, space saving DIN housing -
Protector housing positions and mounts
easily to standard 35mm Top Hat DIN
thanks to innovative DIN foot with
locking feature.
Remote display for optimal
protector mounting - Remote displays enable convenient status
checking, whilst the protector unit is
mounted close to the supply for best
practice short connecting lead lengths.
Remote monitoring facility -
D1 protectors can easily be linked to
building management systems, control
room buzzers or lights for clear, remote
pre-failure warning.
Effective fault and pre-failure warning -
Advanced pre-failure warning to ensure
your equipment never goes unprotected,
with Phase loss and N-E supply fault
warning included as standard.
Designed to deliver the most flexible
mains power surge protection
solution in today’s marketplace, the
ESP D1 protector offers both technical
and economic advantages over
standard Surge Protection Devices.
Tested to the latest EN/IEC standards,
the ESP D1 protector combines industry
leading low let-through voltage with mains
Type 1+2+3 protection within a highly
compact, maintenance-free unit.
The popular 230/400V single and three phase
units limit 6000V transient overvoltages to
just 600V (Class III test).
This level of protection is achieved between
all conductors (full mode protection) ensuring
all transient paths (common and differential
modes) to equipment are protected.
ESP D1 series are also available for 120/208V
and 277/480V single and three phase systems.
A choice of LED or LCD displays is
available, with optional remote mounting,
to provide easy, hassle-free status checking.
The display can be mounted in the most
convenient position for viewing and use (e.g.
externally on the front of a distribution panel)
whilst the compact protector unit sits safely
within the panel (mounted conveniently on a
DIN rail) allowing short connecting leads to the
incoming supply for optimal protection. This
flexibility also saves installation time and cost.
Data Sheet
|
It’s essential that a Surge Protection
Device (SPD) provides continuous
protection against lightning surges
and transient overvoltages.
The unexpected failure of an SPD
would place electronic systems at
serious risk.
Therefore, maintaining and monitoring your
SPDs is a highly important task.
For small scale installations, regular manual
checks can be made, however, for larger scale
implementations or installations with remote
operations, such as telecoms towers or wind
farms, a more in-depth control and
management process is required.
The Furse ESP D1 protector provides the
most practical, scalable solution for all
such scenarios.
ESP D1 incorporates both local and remote
advanced pre-failure warning to ensure your
electronic systems are never left unprotected.
In addition to the protector’s own status,
the ESP D1 warns of power loss and
potentially dangerous neutral to earth
voltages.
Advanced pre-failure, phase loss and high
neutral to earth voltage warning is displayed
locally via the back-lit LCD screen, or via LED.
For remote failure warning, the ESP D1 can
be linked directly or via telecom modem to
a building management system, buzzer or
light via the Active Volt-free Contact within
the unit.
