Adjustable supplies for odd-voltage
racks
Schroff has expanded its range of maxpower 19in-compatible AC/DC switching regulators to provide seamless coverage of the full voltage range between 4.5 and 30V.
Schroff has expanded its range of maxpower 19in-compatible AC/DC switching regulators to provide seamless coverage of the full voltage range between 4.5 and 30V Applications in industry and telecommunications that require nonstandard voltages can also enjoy the benefits of the powerful maxpower series, with the new maxpower LR and UR modules

Schroff, one of the industry's leading manufacturers of CompactPCI Microcomputer Packaging solutions, has unveiled a complementary range of 19" power supplies.
Cut-down prices for CPCI
Europac Integral offers all the benefits of a standard CPCI system including high stability, robustness and EMC shielding but at a far-reduced cost.
These modules offer the user almost laboratory device quality, yet at the price of a standard power supply.
The Max LR (lower range) unit is designed for output voltages of 4.5 to 17V, while the Max UR (upper range) module operates between 16 and 30V.
The required voltage can simply be selected easily on the front panel using a screwdriver.
Current limiting is based on the V/I principle for trouble-free operation of all types of loads, including motors and battery chargers.
As with existing maxpower units, the new power supplies can deliver an output power of up to 100W in a module just 6HP wide.
This is equivalent to a power density of up to 16W/HP.
Suitable for both redundant and hot-swap operation; the modules represent the ideal solution for high availability systems.
In a redundant system, the CSB (current share bus) guarantees equal distribution of the current from the interconnected n+1 power supplies.
An integral redundancy diode isolates the individual power supply units from the system and guarantees that a total system short-circuit does not occur if just one unit is faulty.
The switching regulators are compliant with standard EN61000-3-2-A14 thanks to active power factor correction.
