| MODEL RANGE |
| General |
| New PL-P series units offer remote control and read-back using analog, RS232, USB, LAN (LXI) interfaces. They retain all of the capabilities of the New PL Series when under manual control. All of the specifications from the previous page therefore apply to the equivalent models in the New PL-P series. The following specifications are additional. Versions with a GPIB interface are also available - see below. |
| Model Range |
| PL068-P |
0 to 6V at 0 to 8A |
| PL155-P |
0 to 15V at 0 to 5A |
| PL303-P |
0 to 30V at 0 to 3A |
| PL601-P |
0 to 60V at 0 to 1.5A |
| PL303QMD-P |
2 x (0 to 30V at 0 to 3A), or 1 x (0 to 30V at 0 to 6A) |
| PL303QMT-P |
As PL303QMD-P plus 0 to 6V at 0 to 8A |
| PLH120-P* |
0 to 120V at 0 to 750mA |
| PLH250-P* |
0 to 250V at 0 to 360mA |
| * Details and specifications are covered in a separate brochure (PLH and PLH-P series). |
| DIGITAL BUS INTERFACES - RS-232, USB, LAN (LXI) |
The standard PL-P product offers 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 output terminals.
Note: Remote/Local Sense, and Operational Mode (PL303QMD/T-P) are manually selectable only. |
| RS-232 |
Standard 9-pin D connector. Baud rate 9,600. |
| USB |
Standard USB 2.0 connection (backwards compatible with USB 1.x). 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 INTERFACE (Option G, factory fit only) |
Option G adds a GPIB (IEEE-488) interface.
This is in addition to the RS-232, USB and LAN interfaces of the standard PL-P product. The interface conforms with IEEE-488.1 and IEEE-488.2. |

| Voltage Setting |
| Setting Resolution |
1mV |
| Setting Accuracy |
± (0.05% +10mV) |
| Current Setting |

± (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) |
| OVP and OCP PROTECTION |
| Measure-and-compare over-voltage and over-current protection are implemented in firmware and can be set via the remote interfaces only. Output trips Off for OVP and OCP conditions. |
| Setting resolution |
10mV and 1mA. |
| Response time |
typically 500ms |
| 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 and PL303QMT-P do 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 = 100kΩ |
| Set Current Input |
± (0.5% +0.005A); Input Impedance = 64kΩ |
| Voltage Output |
± (0.3% +10mV); Output Impedance = 125Ω |
| Current Output |
± (0.5% +0.005A); Output Impedance = 125Ω |
| Note that Analog control of current can not be used with the low current range selected. |
| 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 and PL303QMT-P do not have this facility. |
| REAR TERMINALS |
| Power and sense connections are duplicated on the rear panel using a screw-less connector block. |
