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) / NEMA 3 free standing steel cubicles suitable for external use, or more challenging internal environments
AquaStop: (-AS)	PCB protective coating offering protection against damp and moisture ingress
Alternative Switch Arrangements: (-T2 or T3)	Alternative Input, Output and Bypass Switching arrangements Type 2 (T2) style switch arrangement consists of a motorised input air switch and output / bypass changeover switch, with full electronic interlocking to prevent inadvertent mis-operation > Type 3 (T3) style switch arrangement similar to the Type 2 arrangement, but utilising separate motorised air output and bypass switches, with full electronic interlocking to prevent inadvertent mis-operation
Additional Metering: (-ADM)	Additional Digital Metering for - Input Volts - Frequency - Power Factor
4 Pole Switches / Breakers: (-FP)	As standard ESR Stabilisers utilise 3 Pole Switches / Breakers. As an option 4 Pole alternatives can be supplied.
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

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) / NEMA 3 free standing steel cubicles suitable for external use, or more challenging internal environments
AquaStop: (-AS)	PCB protective coating offering protection against damp and moisture ingress
Alternative Switch Arrangements: (-T2 or T3)	Alternative Input, Output and Bypass Switching arrangements Type 2 (T2) style switch arrangement consists of a motorised input air switch and output / bypass changeover switch, with full electronic interlocking to prevent inadvertent mis-operation > Type 3 (T3) style switch arrangement similar to the Type 2 arrangement, but utilising separate motorised air output and bypass switches, with full electronic interlocking to prevent inadvertent mis-operation
Additional Metering: (-ADM)	Additional Digital Metering for - Input Volts - Frequency - Power Factor
4 Pole Switches / Breakers: (-FP)	As standard ESR Stabilisers utilise 3 Pole Switches / Breakers. As an option 4 Pole alternatives can be supplied.
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
