Specifications:
The EnvisionTEC Power Protection System (EPPS) model 52022-53R has a power rating of 250 VA/200 Watts. It features a low distortion sine wave inverter waveform with a typical transfer time of 7 ms and operates at a frequency of 50 Hz. The system has an efficiency of 86% without the charger and supports an input voltage of 230 volts with a current of 1.25 amps. The output voltage is also 230 volts with an output current of 0.86/1.08 amps. The input voltage range without using the battery is 184 - 276 volts, and the output regulation is +10% on mains and +5% on battery. The backup time at full load is greater than 5 minutes. Communication interfaces include RJ11 and USB ports. The shipping weight is 23 lbs (10.4 kg).

Noise Rejection and Surge Voltage:
The system provides noise rejection and isolation, ensuring noise output voltage is less than 10V in normal mode and less than 0.5V in common mode. It withstands surge voltages tested to ANSI/IEEE C62.41 Cat. A & B standards.

Warranty and Support:
The electronics and transformers are warranted for five years, while batteries have a two-year warranty. Specific conditions apply to battery life, especially for products regularly disconnected from AC mains power.

Controls and Interfaces:
The front panel includes power on/off, test, load level LED gauge, battery charge LED gauge, voltage manager nominal LED, on battery LED, and fault LED. The rear panel features an IEC C14 inlet, four IEC320 C13 receptacles, RJ11 and USB ports, and a circuit breaker. The internal battery is user hot-swappable, with a type of 12 volt, 9AH, and a recharge time of 6 to 10 hours to 90% and 24 hours to full charge.

Environmental Conditions:
Operating temperature ranges from 0 to +40°C (32 to 104°F), with shipment and storage temperatures from -20 to +60°C (-4 to +140°F). Humidity is 5-90% non-condensing, and altitude is 2,000m (6,500 ft) max operating and 15,000m (49,000 ft) max for shipment and storage.

Compliance:
The system complies with safety agency and EMC standards, including UL1778 4th edition, EN62040-1-1, and various IEC standards for immunity and disturbances. It is also RoHS compliant.
