Convertors feature tight load regulation
New DC/DC convertors suit a wide variety of board level power applications requiring 3W of regulated output power, input/output isolation, miniature package size and low component cost.
Modules may be configured for hot-swap or N+1 power redundancy and optional external battery backup provides a full no-break power solution.
StrongBox power cassettes are available with active power factor corrected universal AC or 12, 24 or 48V DC input and are self cooling front-to-back, allowing maximum system density.
The system is ETSI standard compatible and meets EN55022 class B and FCC 68 part 15.
The operating temperature range is 0 to +50C with no derating, and all modules are overload, short circuit, overtemperature and overvoltage protected.
Each StrongBox hub can hold up to three modular power convertors from a range of over 20 different configurations.
The AC input modules offer standard single output voltages of 48, 24 or 12V DC.
Other AC input models are available for rectifier/battery charging use or battery backup operation and microwave transmitters.
Two other AC input modules provide multiple outputs of either dual 5V DC or for telecomms applications triple outputs of 3.3, 5 and 12V DC.
