  Digital Bus Interfaces - RS-232, USB, LAN (LXI)

Full remote control and read-back using RS-232, USB or LAN (LXI-C). All interfaces are at ground potential and opto-isolated from the outputs.

Note: Remote/Local Sense, and Operational Mode (PL303QMD-P) are manually selectable only.

RS-232

Standard 9-pin D connector. Baud rate 19,200 max.

USB

Standard USB hardware connection. Operates as a virtual COM port.

Ethernet (LAN)

Standard 10/100 base-T hardware connection. ICMP and TCP/IP Protocol for connection to Local Area Network or direct connection to a single PC.

LXI Compliance

LAN interface is compliant with LXI-C. (LXI is the abbreviation for Lan eXtensions for Instrumentation).

GPIB (only with option G)

Conforms with IEEE-488.1 and IEEE-488.2.

Digital Programming Performance

Voltage Setting

Setting Resolution: 1mV
Setting Accuracy: +/- (0.05% +10mV)

Current Setting

Setting Resolution: 0.1mA (0.01mA on 500mA range)
Setting Accuracy: +/- (0.3% +0.005A) to 3A, +/- (0.5% +0.005A) to 6A, +/- (0.3% +0.5mA) on 500mA range.

Programming Speed

Command Delay: Typically <80ms (this must be added to any of the figures below)
Voltage Up Time: Typically <45ms* to 1%
Voltage Down Time: Typically <20ms* to 1% (full load); typically <150ms* to 1% (no load)

* The up and down times vary with model, current range and voltage step size. More information is contained in the operating manual which can be downloaded from our web site.

Analog Remote Control (single output models only)

Non-isolated analog voltage control of voltage and current. Analog control outputs are also provided to enable easy parallel connection of multiple units in a master-slave configuration.
Note that the PL303QMD-P does not have analog remote control.

Scaling

Reference Point: All control voltage are referenced to the positive output terminal
Set Voltage Input: 0V to 10V sets 0 to 100% of rated output (e.g. 0 to 30V for PL303-P).
  Alternative scaling of 0V to 5V (selectable using internal link).
Set Current Input: 0V to 10V sets 0 to 100% of rated output (e.g. 0 to 3A for PL303-P).
  Alternative scaling of 0V to 5V (selectable using internal link).
Voltage Output: 0 to 100% of rated output voltage generates 0V to 5V.
Current Output: 0 to 100% of rated output current generates 0V to 5V.

Accuracy

Set Voltage Input: +/- (0.3% +10mV); Input Impedance = 100kOhm
Set Current Input: +/- (0.5% +0.005A); +/- (0.5% +0.5mA) on 500mA range

Input Impedance = 64kOhm

Voltage Output: +/- (0.3% +10mV); Output Impedance = 125Ohm
Current Output: +/- (0.5% +0.005A); +/- (0.5% +0.5mA) on 500mA range; Output Impedance = 125Ohm

Remote Analog On/Off Control (single output models only)

Non-isolated terminal which sets the output to Off when pulled low by gate signal or relay closure. Signal is reference to the positive output terminal.
Note that the PL303QMD-P does not have this facility.

Rear Terminals

Power and sense connections are duplicated on the rear panel using a screw-less connector block.
Digital Bus Interfaces - RS-232, USB, LAN (LXI)

NOTE: The above specifications are additional to the Manual Control specifications which can be seen Here.
