General

Capacitance CON2 - Case 3.2 nF

Operating temperature – 20 to + 50 °C

Storage temperature – 40 to + 85 °C

Humidity max. 95% RH, non condensing, up to 40 °C

max. 75% RH, non condensing, up to 50 °C

Isolation voltages CON2 - CON1 1000 VDC Reinforced isolation acc. EN60950-1 / EN61010-1

Isolation test voltage
Minimum creepage distance

Specifications are measured at an ambient temperature of 25 °C ± 5 °C unless otherwise noted.

Note1: The four analog channels are factory-calibrated within 0.1 % for 5 V input and output voltages.

Selecting a 10 V input and/or output without re-calibrating can introduce an extra full scale error of 0.1 %.
Offset, full scale error, non-linearity and temperature coefficient have to be added to the specifications of the power supply.

Note2: Reinforced isolation is available only when the ISO AMP is built inside a Delta Elektronika power supply.
