More and more the traditional power supplies for CompactPCI systems have reached their perfomance limits. Usually, the simplest solution would be to increase the performance of the system with a third or fourth supply. However, this is not possible, as only two power supply slots with exact mechanical dimensions are provided for in the cPCI standards.
To solve this, Schroff has extended its maxpowerPro range and developed two power supplies (AC/DC and DC/DC) with equal dimensions (6 U/8 HP/160 mm deep), which fulfil the demands of users in the telecom, automation and MSR technology sectors through higher performance density and increased efficiency.
The maxpowerPRO power supplies are now available with an output performance of 400 W and 83% efficiency. With an AC input of 85 to 264 V a.c. or a DC input of 36 to 72 V d.c. they can be used in a broad range of areas. The units supply the 3,3 V, 5 V and ±12 V demanded by the CPCI standard, with 80 A at 3,3 V and 50 A at 5 V. The current share bus guarantees even current distribution during parallel switching at the ports in redundant operation (N+1). The temperature range at full performance has also been increased to 55°C.
These hot-swap capable units are fitted with the P47 connector (as per cPCI standard) and have all relevant certifications (CE, TÜV, UL and CSA).
