The Bull''s front panel is simple, with just three
LEDs. The on-off switch, the two power outlets and the RS 232 port are all on the back

The Bull Power 600 emerged an average performer, with
a switchover of 6.2 ms and a backup time of 8 minutes. It was able to regulate output to
only 15 percent on either side, and had very high battery float voltages. Nor was it able
to start an additional 250 VA load on battery and tripped. When short circuited, it
survived, tripped and restarted via the on-off.
