Application and selection
A candidate for insulation supervision of suitably designed converter, battery or auxiliary IT systems. Confirm the earthing arrangement and system leakage capacitance before selection. The iso685-D has an integrated display; it is distinct from the external-display and ruggedised variants. Higher system voltages require a compatible coupling device and verified application design.
Information for your quotation
Provide AC/DC system voltage, earthing arrangement, converter topology, estimated leakage capacitance, auxiliary supply, alarm interface, quantity and delivery postcode. Identify any coupling device or environmental requirements.
