AMBIENT OPERATING TEMPERATURE
-5°C to +40°C
THERMAL OVERLOAD
The K1826 and K2826 filter socket incorporates a
thermal overload device in the RFI filter section.
Overload current causes temperature rise, resulting in
automatic ‘trip out’. The overload device will re-set as
the temperature falls.

Filtered Switchsocket Outlets (Logic Plus and Albany Plus)
Description
A range of sockets in the Logic Plus and Albany Plus styles, designed to combat
interference to or data losses on sensitive electrical products and systems due to
mains borne voltage spikes and RFI.
Such systems include:
l Computer or microprocessor based equipment
l Telecommunications systems
l Electronic measurement equipment
l Cash registers
l Audio visual and hi-fi equipment
These products can be quickly installed as replacements for existing twin 13A
sockets or in a new installation.
Fitted with two earth terminals to provide a double earth facility for use when
installations require a high integrity protective connection as specified within the
latest edition of BS 7671.
Filter cassettes
Filter cassettes are supplied with sockets and have an LED which shows green
under normal conditions but will turn red or extinguish when a replacement cassette
(K1800WHI) is required. An alarm will also beep at 5 second intervals to indicate
replacement necessity. It can be de-activated if required.
