Origin: UK

Warranty: 12 months


OUTPUT SPECIFICATIONS:

-Voltage/Current Levels:

+Voltage Range: 0V to 60V

+Current Range: 0A to 50A.

+Power Range: Up to 1200W 

+Operating Mode: Constant voltage or constant current with automatic cross-over and mode indication.

-Output Setting:

+Voltage Setting: By floating point numeric entry or rotary jog wheel; resolution 1mV.

+Current Setting: By floating point numeric entry or rotary jog wheel; resolution 10mA.

+Setting Accuracy: Voltage - 0.1% ± 2mV; Current - 0.3% ± 20mA

+Setting Stores: Up to 10 set-ups can be saved and recalled via the keyboard 

-Keyboard & Rotary Control:

All functions, including the selection and set-up of the remote control interfaces, can be set from

the keyboard. The rotary Jog control can be used to adjust output voltage and current settings in a

quasi-analogue mode. The output to be controlled is first selected with the appropriate Control key.

-Output Performance:

+Load regulation: <0.01% +5mV (CV mode) for any load change within the PowerFlex envelope, using remote sense.

+Line regulation: <0.01% +5mV for a 10% line voltage change.

+Ripple & Noise: Typically <3mV rms, <20mV pk-pk, (20MHz bandwidth).

+Transient Response: <250µs to within 100mV of set level for 5% to 95% load change.

+Temp. Coefficient: Typically <100ppm/oC.

+Sensing: Selectable local or remote sensing.

- Output Protection:

+External Voltage: Output will withstand forward voltages of up to 70V. Reverse protection by diode clamp.

+Power Limit: Automatic protection within PowerFlex control system.

+Fault Trip: The output will be shut down if any of the four trip conditions listed below occur.

+Over Voltage (OVP): Settable 2V to 65V in 0.1V steps

+Over Current (OCP): Settable 2A to 55A in 0.1A steps

+Over Temperature: Monitors internal temperature rise to protect against excess ambient temperature or blocked ventilation slots.

+Sense Error: Monitors the voltage between the remote sense terminals and output terminals to protect against mis-wiring.

- Output Switching:

Push switch operating electronic power control. LED indication of On state

- Connection:

+Output Terminals: Front and rear output terminals. Safety terminals accepting 6mm wire diameter, 

6mm plugs or 8mm spades at 50 Amps max, or 4mm plugs at 30 Amps max.

+Sensing Terminals: Screw-less terminals on front panel and on rear panel.

METERING

- Display Type: Large dot-matrix black-on-white backlit LCD.

- Meter Function: 5 digit voltage meter and 4 digit current meter. Display of limits values, memory contents etc. Wide range of alpha-numeric messages/menus.

- Limits Display: Limits settings can be displayed simultaneously with measurements.

- Meter Resolution: Voltage: 1mV. Current: 10mA

- Meter Accuracy: Voltage: 0.1% of reading ± 2 digits (CI mode and Unreg); Current: 0.3% of reading ± 2 digits (CV mode and Unreg)

- Additional Metering Functions:

+V x A Display shows calculated power in watts. Resolution 0.1W.; Accuracy 0·5% ± 0·1W

+V/A Display shows calculated resistance. Resolution up to 5 digits.; Measurement uncertainty is shown on display.

ANALOG & LOGIC INTERFACE

-Analog Remote Control and Monitoring:

Non-isolated inputs and outputs to set voltage and current limit and to monitor actual output voltage and current. These signals are referenced to the negative output and have a range of 0 to 10V

or 0 to 5V (selectable via the keyboard). Note that the analog control voltage is digitised within the

power supply.

Control Accuracy: Voltage: 0.3% ± 4mV; Current: 0.5% ± 40mA

Monitor Accuracy: Voltage: 0.3% ± 4mV; Current: 0.5% ± 40mA

-Logic Control Input and Output:

LOGIC IN is a rear-panel opto-isolated input that is activated at an input current greater than

approximately 1mA. User can set LOGIC IN (via the keyboard) to enable the output, disable the

output, or be ignored when it is activated.

LOGIC OUT is an isolated rear-panel open-collector output that will sink up to 2mA when activated

(‘switch closure’); the maximum voltage that can be applied to LOGIC OUT is 30VDC. User can set

LOGIC OUT to be ‘closed’ or ‘open’ for output enabled or disabled, current limit (CI mode), power limit (UNREG mode), or for any fault trip.

GENERAL SPECIFICATIONS:

- Input:

AC Input: 110V to 240V AC ±10%, 50/60Hz. Installation Category II.

Input Power: 1600VA max.

- Temperature & Environmental:

Operating Range: +5ºC to +40ºC, 20% to 80% RH
