Implies on-board voltage regulaon.<br />

WPF-02 The NRWD shall tolerate and run This corresponds to Oo Bock,<br />

normally when powered with a Moon Control and other systems.<br />

voltage in the range (6 V, 12 V). The Upper limit possibly to be relaxed<br />

range of usable voltages should be<br />

as wide as (5 V, 18 V).<br />

(lowered).<br />

WPF-03 The NRWD shall tolerate supply E.g. shung down the controller<br />

voltage in the range (0 V, 12 V) be<strong>for</strong>e the voltage gets dangerously<br />

without exhibing unpredictable low, may otherwise damage Flash<br />

behaviour and without geng and EEPROM content etc.<br />

damaged.<br />
