powerMod Operation and Signals
powerMod Enable/Inhibit
Each powerMod may be enabled/inhibited by means of an
appropriate signal applied to an opto-isolated input on pins J3
pin 5 (positive) and J3 pin 6 (negative), on powerMods XgG to
XgL. Inhibit is available by means of an appropriate signal
applied to an opto-isolated input on J3 pin7 on XgE, on J3 pin
3 and pin 7 on XgF ( the output voltage of the powerMod will be
fully inhibited to 0V) and pin J3 pin5(positive) and J3 pin 6
(negative) on powerMods XgA to XgD . Turn-on delay from AC
in and Global Enable is typically 2ms but is load dependant.

Minimum current required is 1.7mA

powerMod Start-Up and Shutdown
powerMods are designed such that when input power is
applied, all outputs rise to their set point voltage simultaneously.
Likewise, when input power is removed all outputs commence
to drop simultaneosly and reach Zero potential simultaneously.
Outputs can be sequenced using the enable function in order to
allow controlled start up if required.
See plots for start-up and shutdown characteristics.
