Main output voltage range ±10.0V
Main output voltage resolution < 20µV
Main output voltage stability < ±0.2mV
Main output voltage drift Depends on output current drift and size of the
inductive load
Line regulation < ± 0.005% (SMPS supply unit backed by a PWM
driven class D amplifier prevents supply voltage
ripple reaching output).
Maximum current ramp rate 1200A/min
Minimum current ramp rate 0.005A/min
Maximum load inductance 1000H
Maximum persistent switch heater current 120mA (11.5V compliance limit)
Persistent switch heater current stability < ± 0.01mA
17.4 Sensor inputs
Item Specification

Constant voltage Typically <10 mV
PTC resistance range 5 ohms to 3 kohms
Constant current
0.1 to 1000 A
Sensors to be connected with four wires (pins 1, 3, 4 and 5) of 9-way D-connector on iPS.
Pin 2 is sense shield.
Sensor ADC resolution 24 bit

The MercuryiPS
can accommodate thermocouple sensors with cold-junction compensation (CJC).
can accommodate silicon-diode sensors (constant current supply).
can detect short-circuit inputs, open-circuit inputs, and inputs that are shorted to ground.
can store sensor calibration files.
can automatically set range-limits from the calibration file.
The user does not need to set the zero or the span for calibrated sensors.
