GENERAL

1.1 SUMMARY

This specification defines the electrical and mechanical characteristics and requirements for a continuous-duty single-phase, solid-state, uninterruptible power system. The uninterruptible power system, hereafter referred to as the UPS, will provide high-quality AC power for sensitive electronic equipment loads. UPS is not designed to support large inductive or half-wave rectified loads, for example: motors, compressors, vacuum pumps, electric drills, laser printers, hair dryers.

1.2 STANDARDS

The UPS is designed in accordance with the applicable sections of the current revision of the following documents. Where a conflict arises between these documents and statements made herein, the statements in this specification shall govern.

1.3. SYSTEM DESCRIPTION

1.3.1 Modes of Operation

The UPS is designed to operate as a true on-line double conversion system in the following modes:

A. Normal - During normal operation, utility power provides energy to the UPS. The filters, the power factor correction circuit and the inverter process this power to provide computer-grade power to connected loads. The UPS maintains the batteries in a fully charged state.

B. Battery - The UPS will enter Battery mode if there is an extreme power surge, extreme power drop, or utility failure. The battery system supplies power through the DC-to-DC converter to the inverter to generate computer-grade power for the connected load.

C. Recharge - Once utility power is restored, the UPS resumes normal operation and the Battery Charger begins recharging the battery.

D. Bypass - Bypass mode provides an alternate path for utility power to the connected load in the unlikely event of a UPS malfunction, such as overload, overtemperature, or an internal circuit failure.

E. Automatic Restart - Upon restoration of utility / mains AC power, after a utility mains AC power outage and complete battery discharge, the UPS automatically restarts and resumes supplying power to the critical load and the battery charger automatically recharges the battery.

1.3.2 Design Requirements

A. Voltage: Will operate at either 120/208V or 120/240V by sensing the utility phase angle and configuring the dual inverters to the same angle: 120 or 240 degrees, (or) 180 degrees. Nominal input/output voltage specifications of the UPS at rated load are:

Input:

The UPS will automatically configure itself to operate from 120 / 208V, 60/50 Hz, (or) 120 / 240V, 60/50 Hz without the use of selector switches or voltage taps. Input wiring must be 3-wire (L1, L2, N) -plus-ground. Using the included configuration program the UPS can be configured to operate from the following alternate AC voltages:

127 / 220V, 115 / 230V, 110 / 220V, 100 / 200V.

Output:

Output voltage is present at terminals L1, L2, and N. The output voltage is automatically set to match input voltage of 120 / 208V, 60/50 Hz, (or) 120 / 240V, 60/50 Hz.

Voltage measured between L1-N and L2-N: 120VAC +3%, 60/50Hz.

L1-L2: 208 or 240VAC (auto sensing to match input phase angle) + 5%, 60/50Hz.

Using the included configuration program the UPS can be configured to provide the following alternate voltages:

127 / 220V, 115 / 230V, 110 / 220V, 100 / 200V, all voltages +3% at 60 or 50 Hz.
