6.7.1.6 Zo Program
The Zo Program soft key is used to Enable or
Disable the programming output impedance
function of the power source. When Enabled,
the R and L component of the output
impedance are displayed in the MORE
SETTING area of the screen.
Default settings are Zo R = 0.00
Ω
and Zo L =
0.00 mH. By touching either field, the user
can set a value for R and L to obtain a specific
output impedance.
Available set value ranges for Zo Program
are:
Zo R = 0.01 ~ 1.00
Ω
Zo L = 0.01 ~ 1.00 mH
The example to the right shows a setting of
0.5 resistive only. The output voltage will
now drop as a function of load current by the
amount of current x 0.5.
WARNING
The upper limit for Programmable output impedance is 1.0 Ohm / 1.0 mH. If L is more than
0.5 mH and the output voltage is low (e.g. less than 100Vac), any large load current may
cause an unstable output voltage. It is important that the user adjusts the L value slowly
while monitoring the output voltage and listening for any unusual sounds coming from the
power source. If any unusual high frequency output voltage is observed or any abnormal
sound is heard,
DO NOT
use this feature. Instead, use an external actual impedance circuit
in series with the load.
