power supplies are connected via PIP401 devices to a shared load. An auxiliary
supply provides the PIP401 devices with 12 V. Power supplies with forced current
sharing capability are ideal for this application. The remote connection to each
PIP401 is taken from a point close to the load in order to compensate for the effects
