10.0 Specifications
10.1 Input
Nominal input voltage:
single phase 230 Vac.
Nominal input frequency: 50 or 60 Hz, selected by option switch #4.
10.2 Transfer Characteristics
Frequency limits for on-line operation: ±5% of the nominal 50 or 60 Hz.
Low input voltage limit for on-line operation: 196 Vac., may be set lower.
10.3 Output Characteristics
Maximum load:
250 VA or 170 W, 400 VA or 250 W, and 600 VA or 400 W for models
250, 400 and 600 respectively.
Nominal output voltage: 225 Vac, ±5%. When verifying UPS on-battery output voltage,
use only a true rms responding voltmeter.
Frequency regulation: 50 or 60 Hz, ±3% unless synchronized to the utility.
Waveshape: stepped approximation to sine wave; peak and rms values equivalent to the
utility.
Protection: electronically overcurrent and short circuit protected, overload shutdown is
latched.
10.4 Battery and charger
Battery type: maintenance free lead-acid, sealed and leakproof.
Typical service life: 3-6 years, dependent on number of discharges, temperature.
Low battery signalling:
> 2 minute audible tone, interface port signal.
Recharge time: 6 to 10 hours, dependent on load and length of utility outage.
