AMPCONTROL BRAND GUIDELINES

ELV – our next generation
earth leakage relay
AMPCONTROL
BRAND GUIDELINES
Ampcontrol’s ELV provides wide bandwidth earth leakage
protection as per AS/NZS2081:2011. It is designed for use on
earth fault limited systems, particularly coal and metal mining
applications that may include Variable Speed Drives.
The ELV relay provides a definite time operating characteristic
with adjustable trip sensitivity and time delay. It latches when
tripped and provides normally open and change-over relay
contacts. The relay supports an external reset switch, and a
4-20mA interface allowing external monitoring. For security
the ELV has provision to prevent unauthorised adjustment of
the trip settings.
DIN rail or panel mounted through a 69 x 39mm cut out.
When panel mounted, the front of the ELV relay is designed to
provide IP56 ingress protection.
Features
• AS/NZS 2081:2011 compliant
• Wide operating bandwidth (5Hz to 10kHz)
• Increased current range (down to 30mA)
• Fail safe operation
• Continual monitoring of the toroid
• Adjustable trip level and time delay settings
The user has the ability to switch the relay between wideband
(up to 10kHz), narrowband (power frequency) and weighted
frequency mode (up to 10kHz, high frequency corrected).
The relay is housed in a stainless steel case and can be either
