How many number of ABL1 power supplies we can connect parallel or series connection.

The outputs of Switch Mode Power Supplies can NOT be connected in either series nor parallel unless they are specifically designed to allow for multi-unit synchronization. Very few SMPS devices are designed for this.  The reason is that each SMPS is switching 20,000 - 80,000+ times per second. If you connect their outputs together without them being perfectly syncronized, they will not share the load properly and there can be very large voltage transients created which will destroy the SMPS components and possibly even the load you have connected to them.  The ABL1 power supply has a feature to connect maximum of two power supplies in series or parallel. You cannot connect more than that in any case. This information is also available in ABL1 power supplies specification sheet.
