Output Protection:
Output will withstand an applied forward voltage of up to 50V (O/P1 and
O/P2), or 80V O/P3. Reverse protection by diode clamp for reverse currents
up to 3A.
Over-voltage Protection
(OVP) Trip:
Outputs 1 and 2: 1V to 40V. Output 3: 1V to 80V. Output trips off for OVP.
Resolution 100mV. Response time: typically 500us. Accuracy: ± (2% ±0.5V)
Over-current Protection
(OCP) Trip:
Measure-and-compare over-current protection is implemented in firmware.
Output trips off for OCP. Setting resolution: 10mA. Response time: typically
500ms.
Accuracy: ± (0.3% ±2digits)
Over-temperature
Protection (OTP) Trip:
The output will be tripped off if a fault or blocked ventilation causes the
internal temperature to rise excessively.
METER SPECIFICATIONS (Each Output)
Voltage/Current Meters
5 digit meters for O/P 1; 4 digit meters for O/P 2 and O/P 3.

O/P2 and O/P3: 5-digits. Resolution 0,01W. Accuracy: 0.5% of reading ±
3 digits
SETTING MEMORY STORES
Stores for Individual
Outputs:
50 store positions for each output. Values stored are Range, Voltage,
Current, OVP and OCP
Stores for All Outputs:
50 store positions operating on all three outputs simultaneously.
Values stored are Range, Voltage, Current, OVP, OCP, Output On/Off,
Current Meter Averaging, Multi-On/Multi-Off Setup
USER INTERFACE
Display:
Black on white backlit graphic LCD, 256 x 112 pixels.
Multiple font sizes and graphic icons.
Soft Keys:
Six illuminated multi-function keys annotated from the display.
Home Screen:
Simultaneous display of meters and settings for all outputs.
Direct access to voltage or current setting for any output.
Individual Screens:
Display of meters and extended settings for an individual output (meters
in larger font). Direct access for all settings for that output.
Numeric Setting:
Floating point numeric entry of voltage, current, OVP or OCP.
Spin Wheel Setting:
Voltage, current and other parameters can be adjusted using the spin
wheel in quasi-analog fashion. Wheel can be disabled.
Menu Screen
System level functions are selected from a scrollable list.
Help Text
Multi-page help text is available for system level functions.
Front Panel Locking:
The lock key can be used to disable front panel control (hold to unlock).
If required locking can alternatively be done using a secure passcode.
