Atandra Energy Pvt. Ltd., with years of experience in Power Conditioning & Energy Management, provides innovative solutions to your power conditioning needs. KRYKARD Servo Stabilisers have set the standard in the industry for product design and quality in over 300,000 installations over the years.

Under‐rated stabilisers are cheaper but break down frequently and have shorter useable life ‐ higher downtime, reduced productivity and higher life‐cycle cost

NO under-rating to make it cheaper

– set in relation to the nominal output voltage for compatibility with

– normally set at 110% of rated full load current but can be altered

Options for additional protection features as required by the machine such as phase reversal trip,

• Under / Over voltage tripmachine requirement

• Current sensing for overload tripbased on machine requirement ensuring genuine protection for equipment and stabiliser

• Protection against 1‐phasing, short circuit & spikes• Manual service by‐pass as a standard feature up to 50 kVA•

Earth leakage protection, lightning arrestors
