Series OMEGA Series OMEGA EDITION 2001 CONFIGURED (MODULAR) UNITS If you cannot find a standard Omega unit which fully meets your Volts Amps Watts Module Number of slots requirements, the Lambda UK Technical Sales support team will 28 3,25 91 D 1 create a customised modular unit utilising the standard modules. If 5 25 125 B 1 your requirements are straightforward you can configure the unit 56 30 B 1 yourself. First list all required output voltage and current ratings (all 12 4 48 C 1 outputs are fully floating - hence polarity can be ignored), multiply the 24 3 72 D 1 voltage and current together to calculate power in watts for each output. Add together all the output powers to arrive at the total N.B. : One slot width = 23 mm wattage in this example the total power is 366W. 4. Now list the converter followed by the modules selected in Volts Amps Watts descending order of current rating 28 3,25 91 Example : MML 400 5B 5B 12C 28D 24D. 5 25 125 This is the part number of your customised unit 56 30 12 4 48 In addition there are options available for either the converter or each 24 3 72 of the modules separately, consult the options table for details. If you need the converter or primary option, enter an ‘X’ after the converter Total power : 366 i.e. MML400 X. If you need the parallelling option on the 28 volt Now proceed as follows: output enter Y5 after the module i.e. MML400 X 5B5B12C28DY524D 1. Select either 400, 600 or 800 watt converter. In the example a 400 watt would be required. 2. Now refer to the module table and select a unit to meet the requirements of the first output in the example, this is 28 volts at 3.25 amps, so a ‘D’ module would be suitable. Prefix this with the required voltage (in this case 28). This gives the module specification as 28D.
