10.0Specifications

10.1Input

Nominal input voltage: single phase 230 Vac.

Nominal input frequency: 50 or 60 Hz, selected by option switch #4.

10.2TransferCharacteristics

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.

10.3OutputCharacteristics

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.

10.4Batteryandcharger

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.
