TTI PL601

The New PL Series is the latest high-performance linear regulated dc power supply range from TTi.

It replaces the original PL series which has been the laboratory power supply of choice for many organisations across the world.

The New PL Series retains the true analog control of the original PL series. but combines it with new digitally based convenience features. higher power density. and superior performance.

OUTPUT

Voltage/Current Ranges

PL155 - 0V to 15V/1mA to 5A; 0V to 15V/0.1mA to 500mA; (75W max.)

PL303 - 0V to 30V/1mA to 3A; 0V to 30V/0.1mA to 500mA; (90W max.)

PL601 - 0V to 60V/1mA to 1.5A; 0V to 60V/0.1mA to 500mA; (90W max.)

PL303QMD - two identical outputs as per PL303. with Tracking and Parallel modes (see Modes section)

Note: Actual maxima for voltage and current are typically 1% greater than the figures given above.

Output Setting & Control

Voltage Setting: By coarse and fine controls.

Current Setting: By single logarithmic control.

Output Mode: Constant voltage or constant current with automatic cross-over. CC indicator in constant current mode.

Output Switch: Electronic. non isolating. Preset voltage and current limit displayed when Output off. 
Output rise time no load <15ms.

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 0.1V to 15V/30V/60V depending on model. 
The range for Vmin is 0 to (Vmax 0.1V).

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 and Noise: Normal mode voltage: <04mv rms="" and="" 2mv="" p-p="" normal="" mode="" current:="" 02marms="" 40ua="" on="" 500ma="" range="" common="" 5ma="" span="">

Load Regulation: Voltage - <001% + 2mV. Current - typically 001% + 500A.

Voltage specification applies for any load change. measured at the output terminals. When using remote sense add 0.5mV per 0.1V drop in the positive output lead (max. sense lead resistance 0.5 Ohm).

Line Regulation: Voltage <001% + 2mV for 10% line change.Current <001% + 250A. for 10% line change.

Temp. Coefficient: Voltage: typically <(50ppm + 05mV)/C; Current: typically <(100ppm + 1mA)/C; 
(100ppm + 01mA)/C on 500mA range.

Output Protection

Output Protection: Output will withstand forward voltages of up to 20V above rated output voltage. Reverse protection by diode clamp for currents up to 3A.

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

Safety Interlocks: Operations that could cause an unpredictable change in voltage or current settings are interlocked with the output switch.

Output Connections

Output Terminals: Universal 4mm safety binding posts on 19mm (075) spacing.
Terminals can accept fixed shroud 4mm plugs. standard 4mm plugs. fork terminals and bare wires.

Remote Sense

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

Sense Terminals: Sprung loaded screw-less terminals.

MODES OF OPERATION (PL303QMD only)

The PL303QMD has four modes of operation - Independent. Isolated Tracking. Isolated Ratio Tracking. 
and True Parallel.

Independent: The two outputs are completely independent and electrically isolated from each other.

Tracking: The two outputs remain electrically isolated. but the voltage control of the Master output sets an identical voltage on the Slave output.

Ratio Tracking: As Tracking. but the Slave voltage can be set to to any percentage of the Master output and will retain that percentage ratio as the Master voltage is varied.

Parallel: All of the power (up to 180 watts) is channelled to the Master output which can consequently supply up to 6 amps. The Slave output is turned off and its meters are blanked.

Both On/Both Off: The Both On and Both Off buttons are in addition to the individual switches for each output. and allow both outputs to be turned on or off synchronously by a single button press.
