Calibration

A high performance linear regulated DC power supply with true analog controls and digital functionality.

Comprehensive features include:

  • Linear regulation: ultra-low output noise and fast transient recovery
     
  • High power density: 90 watts per output from a module taking up minimal console space (150mm width)
     
  • Higher precision: Exceptional line and load regulation; easy-switch remote sense
     
  • Better metering: High accuracy four digit fixed-resolution meters; low current range; current meter averaging
     
  • True analog controls: Quick and intuitive adjustment of voltage and current
     
  • Digital convenience: Unique S-Lock and V-Span functions
     
  • See exactly what's happening: DC output switch - check your settings before applying them; 'view settings' button - check and adjust limits at any time
     
  • Safe and secure to use: Lockable voltage and current settings (using S-Lock); connect via safety binding-post terminals.
     
  • Programmable version 7052P: Includes all of the manual control features of the 7052, but adds comprehensive remote control facilities. RS-232 and USB interfaces.

 

  • 0 to 30V, 0.1mA to 3A (90W max)
  • High accuracy 4 digit meters
  • Fixed resolution for consistency
  • Instant setting lock function
  • Customise voltage range function
  • Linear regulation - low noise
  • Programmable version - 7052P

 

Technical Specifications

Output

Voltage/Current Ranges 0V to 30V/1mA to 3A; 0V to 30V/0.1mA to 500mA; (90W max.)

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 30V 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 Specifications below for details.

Output Performance

Ripple and Noise: Normal mode voltage: <0.4mV rms and 2mV p-p; Normal mode current: <0.2mA rms; (<40μA on 500mA range); Common mode current: <5mA rms 
Load Regulation: Voltage - <0.01% + 2mV. Current - typically 0.01% + 500μA. 
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 <0.01% + 2mV for 10% line change. Current <0.01% + 250μA. for 10% line change. 
Transient Response: <50ms to within 50mV of setting for a 90% load change. 
Temperature Coefficient: Voltage: typically <(50ppm + 0.5mV)/°C; Current: typically <(100ppm + 1mA)/°C; (100ppm + 0.1mA)/°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 (0.75”) 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.

Meter Specifications

Display Type Dual 4-digit meters, 10mm (0.39”) LED.

Voltage Meter

Resolution: 10mV
Accuracy: ± (0.1% of reading + 10mV)

Current Meter

Resolution: 1mA (0.1mA on 500mA range).
Accuracy: ± (0.3% + 0.005A) to 3A; ± (0.5% + 0.005A) to 5A; ± (0.3% + 0.5mA) on 500mA range.
Meter Damping: Normally 20ms, switchable to 2 sec for averaging of rapidly varying loads.
