Range: 0 to 30V at 0 to 3A

Output Setting & Control

Voltage Setting: By coarse and fine controls.

Current Setting: By single logarithmic control.

Low Current Range: Reduces max. current to 75mA and increases resolution to 0.01mA.

Output Mode: Constant voltage or constant current with automatic cross-over.

CC indicator lit in constant current mode.

Output Switch: Electronic, non isolating. Preset voltage and current limit displayed

when Output is off. Output rise time no load <20ms.

View Settings: With the output On, the meters show actual voltage and current.

The preset levels can be viewed and adjusted at any time by pressing

the View Settings button

V-Span

(Voltage Span Control)

The voltage adjustment range can be controlled by digital setting of the end-stop values of

the coarse voltage control to any desired values. The range for Vmax is 1V to 120V or 250V

depending on model. The range for Vmin is 0 to (Vmax – 1V).

S-Lock

(Settings Lock)

Voltage and current settings can be locked by a single button press. Lock accuracy is equal to

the meter accuracy (see Meter Specification).

Output Performance

Ripple & Noise: Normal mode voltage: <2mV rms and 10mV p-p

Normal mode current: <10uA rms ; <1uA rms on 75mA range

Common mode current: <20uA rms

Load Regulation: Voltage - <0·01% + 10mV.

Current - typically 0·01% + 50µA.

Line Regulation: Voltage <0·01% + 10mV for 10% line change.

Current <0·01% + 50µA. for 10% line change.

Transient Response: <250µs to within 50mV of setting for a 90% load change.

Temp. Coefficient: Voltage: typically <(50ppm + 2mV)/°C

Current: typically <(100ppm + 0.1mA)/°C;

<(100ppm + 0.01mA)/°C on 75mA range

Output Protection

Output Protection: Output will withstand forward voltages of up to rated output voltage.

Reverse protection by diode clamp for currents to 3A.

OVP and OCP Trips: Voltage or current measured to be in excess of 105% of the rated

maximum will cause the output to trip off.

Over-temperature: Output trips off for over-temperature.

Safety Interlocks: Operations that could cause an unexpected change in voltage or

current settings are interlocked with the output switch.

Output Connections

Output Terminals: Universal 4mm safety binding posts on 19mm (0·75”) spacing.

Terminals can accept fixed shroud 4mm plugs, standard 4mm plugs, fork terminals and bare wires.

Remote Sense

Sense Selection: Voltage sensing is selected as Local or Remote by front panel switch.

Sense Terminals: Sprung loaded screw-less terminals.

METER SPECIFICATIONS

Display Type: Dual 4-digit meters, 10mm (0·39”) LED.

DIGITAL BUS INTERFACES (PLH-P models only)

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-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). For more information visit: www.tti-test.com/go/lxi

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

DIGITAL PROGRAMMING PERFORMANCE (PLH-P models only)

Programming Speed

Command Delay: Typically <25ms (this must be added to any of the figures below)

Voltage Up Time: Typically <45ms* to 1%

Voltage Down Time: Typically <200ms* to 1% (full load); typically <500ms* 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 - downloadable from our web site.

VARIABLE OVP and OCP PROTECTION (PLH-P models only)

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: 100mV and 0.1mA.

Response time: typically 500ms

ANALOG REMOTE CONTROL (PLH-P models only)

Isolated analog voltage control of voltage and current. Non-isolated analog control outputs

are also provided to enable easy parallel connection of multiple units in a master-slave

configuration.

Control Inputs (Isolated)

Reference Point: Control input voltages are referenced to their own return points.

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 (0 to 750mA for PLH120-P).

Alternative scaling of 0V to 5V (selectable using internal link).

Set Voltage Accuracy: ± (0.3% +100mV); Input Impedance = 10kW

Set Current Accuracy: ± (0.5% +0.5mA); Input Impedance = 10kW

Control Outputs (Non-isolated)

Reference Point: Control output voltages 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.

Voltage Out Accuracy:± (0.3% +100mV); Output Impedance = 125W

Current Out Accuracy: ± (0.5% +0.5mA); Output Impedance = 125W

Note that Analog control of current can not be used with the low current range selected.

REMOTE ANALOG ON/OFF CONTROL (PLH-P 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.

DRIVER SOFTWARE SUPPLIED (PLH-P models only)

IVI Driver

An IVI driver for Windows is supplied. This provides support for common applications such as

LabView*, LabWindows*, HPVEE* etc.

USB Driver

An installation file is supplied which calls a standard Windows* USB driver.
