ADD-ON OPTIONS |
|
Input Isolating
Transformer:
(-PC) |
Through the inclusion of a shielded isolation transformer,
provides enhanced spike & electrical noise (common &
normal interference) suppression and neutral
ground bonding. Delivers what is commonly
referred to as a ‘CLEAN’ supply |
Outdoor IP54
Ingress Protection:
(-IP54) |
Stabiliser presented in an endurable IP54 (BS / EN 60529)

eSpec Upgrade:
(-eSP) |
While we endeavour to keep production costs to a minimum
by sourcing top specification components from
around the globe we realise that some clients have a
requirement for their own designated protection devices
Accordingly we are able to offer our eSpec Pack Upgrade
package which offers the client the short circuit and
overcurrent protection components from their preferred
leading European or American manufacturers |
