An ultra-high efficiency of typically 95.6% at full load and the ability to operate over an ambient temperature range of -40 to +85°C, makes them a suitable choice for the isolated converter in a distributed power architecture supplying power to non-isolated converters. Their open-frame design is optimised for forced air or conduction cooling and an aluminium baseplate option is available for enhanced thermal performance. The conversion technology employs 175kHz fixed frequency switching to help minimise external EMI filtering requirements.
Standard features include output voltage trim and remote on/off, with input undervoltage and overvoltage lockout. The converters are comprehensively protected against output overvoltage, output overcurrent and overtemperature conditions. ADQ600 series converters have an enhanced pre-bias start-up capability and for high current applications two converters can be connected in parallel, automatically using the droop method of current sharing.
Artesyn ADQ600 series converters are low profile units that suit systems with demanding inter-board spacing requirements; the open-frame models have an installed height of 11mm (0.43″), while the baseplate versions require 13.3mm (0.52″).
