PL512 POWER SUPPLY
The PL512 power supply is the second format of DC current power supply made by W-IE-NE-R. It offers up to 12 independent, floating and programmable channels. This equipment generates a very high power density together with a high number of channels.
Our PL512 power supply consists of:
- a 19 ″ standard mechanical rack called a ‘power bin’,
- a power box containing a PFC and 6 slots (1 slot = 1 module = 2 channels),
- dual MDL / MDH modules from 420 W to 550 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 cabinet. Through that the connections and the cable passages are made, in particular via threaded rods and nuts of M4 diameter to pass up to 80 A. On the rear panel there are 6 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’ can accommodate the PFC, the elementary modules and the control card, the USB / Ethernet controller and the digital display system. The power supply to the sector is done by the power box. 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.
In the PL512 power supply 1 up to 6 basic modules can be inserted offering a lot of flexibility.
A large panel of DC voltage is offered for the values 7 V, 16 V, 24 V and 60 V for currents of 6 A, 11.5 A, 20 A, and 30 A. These modules operate with a master-slave configuration. They are programmable and operate in the following 2 regulation modes, voltage and current. They allow the configuration of several parameters: voltage ramps, current trips, temperature supervision, group operations, interlock, etc.
The elementary modules of the PL512 power supply are designed to operate over short (< 5 m), medium or long (> 40 m) distances as well as to deliver on loads of different types (resistive, capacitive and / or inductive ). Three regulation types are provided (fast, medium or slow) in order to meet these constraints and thus eliminating or limiting the effects of overshoot and the 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 PL512 power supply in a larger installation.
