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

Software makes for simple configuration of subrack
Schroff, the 19-inch expert, is the first on the market to offer a software program that allows the customer to configure individual subracks, plug-in modules, sub-units and front panels.
Handle protects CPCI boards in 19in units
Schroff's HLS (High Leverage Self-locking) handle fully complies with the IEEE 1101.10 standard and is suitable for the insertion and extraction of all 19" plug-in units.
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 16V 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 6 HP wide.
This is equivalent to a power density of up to 16 W/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 EN 61000-3-2-A14 thanks to active PFC (Power Factor Correction).
