1.3.4 TRANSIENT RESPONSE
The voltage transient resulting from switching the load from 70% to 100% of full load will
be less than 10% of the maximum output voltage of the supply. The voltage will recover to
±2% of its original value within 650
µ
s for units up to 20v. For units above 20 volts the
recovery time is increased by a factor of V
max
/ 20.
1.3.5 STABILITY
Maximum deviation in either voltage or current mode for an eight (8) hour period is 0.05%
of max. output under conditions of constant line, load and temperature.
1.3.6 REMOTE PROGRAMMING
All EMS models are capable of being remotely programmed by means of an external
resistance, external DC voltage source or an external DC Current source. The remote
programming controls all switching action in the power supply. The following table provides
the remote programming accuracy at full output.
