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 is 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
GPIB (only with Option G)
The interface conforms with IEEE-488.1 and IEEE-488.2
LXI Compliance
LAN interface is compliant with LXI-C. (LXI is
the abbreviation for LAN eXtensions for Instrumentation)
Digital Programming Performance
Voltage Setting Resolution
10mV
Voltage Setting Accuracy
0.05% +50mV
Current Setting Resolution
0.1mA (0.01mA on 75mA range)
Current Setting Accuracy

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.
ANALOGUE REMOTE CONTROL
Isolated analogue voltage control of voltage and
current. Analogue control outputs are also provided to enable easy
parallel connection of multiple units in a master-slave
configuration.
Scaling
Set Voltage Input
0V to 10V sets 0 to 100% of
rated output (e.g. 0 to 120V for PLH120-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 750mA for PLH120-P). Alternative scaling of 0V to 5V
(selectable using internal link)
Reference Point for control outputs
control output voltage are
referenced to the positive output terminal
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
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
Rear Terminals
Power connections are duplicated on the rear panel using a screw-less connector block.

OPTIONS
Rack Mount
(RM450) 19 inch 4U rack mount suitable for up to four
single power supplies, two dual power supplies, or any mixture.
Blanking plates are provided for unused positions. The 4U height
provides limited ventilation space above and below the power
supplies.
Option G
Adds a GPIB (IEEE-488) interface.
This is in addition to the RS-232, USB and LAN interfaces of the
standard PLH-P product.
