PL506 power supply


The PL506 power supply is a DC current power supply of very high density and it can deliver a maximum of 6 independent, floating and programmable channels.

The PL506 power supply consists of the following assembly:

  • a 19 ″ standard mechanical rack called a ‘power bin’,
  • a power box containing a PFC and 6 free slots,
  • basic and independent MEH modules from 500 W to 650 W,
  • an electronic card to control and supervise the modules,
  • an integrated USB / Ethernet controller with an optional multi-line digital display.

The ‘power bin’ mechanism is placed and fixed in a power bay. Through that the connections and cable passages are made, in particular via threaded rods and nuts of M6 diameter to pass up to 150 A.

Its rear panel has 3 SUB-D connectors of 9 pts through which ‘Senses’ returns operate to compensate for line losses due to high currents in the cables.

The power block ‘power box’ is prepared to accommodate the PFC, the elementary modules and the control card, the USB / Ethernet controller and the digital display system.  It has an ‘easy lever’ sliding extraction handle that makes it easy to remove the block without having to remove the cable bundle at the rear. This is a significant time saver in the event of a configuration or maintenance change.

The PL506 power supply offers a wide range of DC voltages among the values ​​7 V, 10 V, 16 V, 30 V and 60 V for currents of 13.5 A, 23 A, 46 A, 80 A and 115 A. These modules operate with a master-slave configuration, they are programmable and operate in the 2 “voltage and current” regulation modes. Via these, several parameters are configurable: voltage ramps, current trips, temperature supervision, group operations, interlock, etc.

The elementary modules are designed to work over all types of distances (from a few meters to more than 40 meters) and can deliver loads of different types (resistive, capacitive and / or inductive). Three regulation types (fast, medium or slow) are planned in order to respond to these constraints and thus eliminate or limit the effects of overshoot and sustained oscillations.

A processor monitors the correct operation of the modules and protects them against illegal modes and faults.

The USB controller enables the control in local mode via the application Musecontrol, the Ethernet interface via SNMP protocol facilitates the integration of the PL506 power supply in a larger installation.
