Calibration

Precision linear regulated DC power supplies with high power density and smart analog controls for voltages up to 120V (7054) or 250V (7055).

Comprehensive features include:

  • Linear regulation: ultra-low output noise and fast transient recovery
     
  • High power density: 90 watts per output from the 7054 and 94 watts per output from the 7055
     
  • 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 versions 7054P and 7055P: Includes all of the manual control features, but adds comprehensive remote control facilities. RS-232 and USB interfaces.

 

  • 7054: 0 to 120V / 0.01mA to 750mA
  • 7055: 0 to 250V / 0.01mA to 375mA
  • 7054: 90W max, 7055: 94W max
  • High accuracy 4 digit meters
  • Fixed resolution for consistency
  • Customise voltage range function
  • Programmable versions available

 

Technical Specifications

Output

Voltage/Current Ranges

7054 - 0 to 120V / 0.01mA to 750mA (90W max.) 
7055 - 0 to 250V / 0.01mA to 375mA (94W max.) 
Note: Actual maxima for voltage and current are typically 1% greater than the figures given above except for the voltage control on the 7055 which is limited to 250.0V

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 & 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)

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 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
