Price/Performance Leadership
The combination of BEST's exceptional microprocessor control and new on-line
transformer and inverter technology makes UNITY/I(TM) Single-Phase the most
efficient, reliable, and cost effective UPS available. The UNITY/I one-piece
solution costs up to 50 percent less than alternatives on the market because
UNITY/I is kilowatt (KW) rated for modern power-factor corrected loads.
Lowest Life-Cycle Costs
With a 96 percent efficiency rating, UNITY/I is a true "Green Machine." So
you realize more than twice the savings on energy costs.
Fault-Tolerant Reliability
It also brings new levels of fault tolerance to the UPS field. With UNITY/I,
built-in layers of redundancy provide alternate power paths to protect your
computers at all times.
Excellent Power Conditioning
UNITY/I is a universal system: it automatically selects frequency (50 or
60 Hz) and allows you to select operating voltages to meet requirements at
any site in the world.
Advanced Self-Diagnostics
UNITY/I incorporates PhonTek(TM) capability, an internal, intelligent monitoring
feature.
Compact and Quiet
And, UNITY/I has the sleek look, small footprint, and whisper quiet operation that fit in any office environment. In fact, UNITY/I is more than twice as quiet (40 decibels at 1 meter) as other UPS models on the market.
Serviceability
Like the Ferrups before it, the UNITY/I is designed and constructed for long life and serviceability. This is not a throw away. It is backed by strong factory support and our own maintenance personnel. (See Service Dept note below)
General Specifications
- Lightning and Surge Protection: Passes ANSI/IEEE C62.41 Categories A3 and B3 test. Zero surge clamping response time. 0.7% LTV. UL1449 listed. 300 joule surge suppression rating. Meets IEC 801-5.
- Isolation (includes output N-to-G bond): Complete from line. Qualifies as a separately derived power source under NEC article 250-5d.
- Noise Rejection: Advanced compound filter elements provide attenuation up to 90dB in normal mode and 50dB in common mode.
- Regulation: Steady-state regulation is ±3% of nominal output voltage. Exceeds recommended CBEMA and ANSI voltage regulation standards for computing equipment under any line, load, or battery conditions.
- Continuous No-Break Power: UNITY/I provides continuous, no-break power during a complete power outage or momentary power interruption.
- Sine-Wave Power: UNITY/I provides sine-wave, computer-grade power with 5% or less total harmonic distortion (THD) at rated KW load. Meets or exceeds CSA C22.2 No. 107.1 for harmonic distortion.
- Load Compatibility: Guaranteed compatible with all computer loads, including power-factor corrected.
- Intelligent, Interactive Interface: RS232 port featuring full-duplex serial communication, alarm contacts, inverter contacts, and Remote Emergency Power Off (REPO). Includes unique PhonTek(TM) remote diagnostic port.
- Reliability Engineered: UNITY/I has a dual-track redundant configuration that utilizes either line or inverter source for power and is designed to meet or exceed an expected MTBF of more than 19 years. American Pro Service Department note: We've had these in the field now for 6+ years and they have been darn near bullet proof. They are generator friendly, very quiet running and extremely efficient in terms of wasted power.
- Protection: Overload alarm and microprocessor-controlled circuit breaker. Optional output receptacles protected by fuses or circuit breakers.
- Overload: 150% surge.
- Frequency: 50 Hz or 60 Hz nominal. On line: output frequency tracks input within adjustable limits (±3 Hz default). On inverter: ±0.15 Hz.
- Temperature: 0°to +40° C operating. Storage from -20° to +60° C (-20° to +40° C if battery is not removed).
- Relative Humidity: 0 to 95% without condensation.
- Ventilation Requirement: Clean, dust-free air, free of corrosive chemicals or other contaminants must be available with proper air circulation.
- High Altitude Operation: Maximum ambient operating temperature drops by 1° C per 305 meters (1,000 feet) above sea level, with the maximum elevation being 3,050 meters (10,000 feet).
