sound a loud tone 2 minutes in advance of shut down due to battery capacity exhaustion. Once shut down, the UPS will return to the periodic beep. The UPS should be turned off at this point to cease the alarm. In the event the UPS encounters a severe overload, the UPS will shut down and emit a loud tone. The alarm is reset when the UPS is turned off.

5.4OptionSwitches

The option switches are located on the rear panel and are set to the down (off) position as supplied from the factory.

5.4.1 Option Switch #1

When option switch #1 is set to the up (on) position in advance of a utility failure, the UPS’s audible utility failure alarm is defeated. When the switch is set to the down position (this is the factory setting), the UPS beeps once every five seconds when the utility voltage has fallen outside acceptable limits. Regardless of the position of this control, the UPS will still sound a loud tone during the low battery conditions. This feature is convenient where brief power interruptions are common and the audible alarm becomes an annoyance.

5.4.2 Option Switch #2 and #3

Option switches #2 and #3 adjust the utility voltage at which the UPS will transfer your computer equipment to the UPS’s alternate power source. Adjustment of the “transfer voltage” is desirable where frequent line voltage excursions or line voltage distortion cause the UPS to transfer many times a day. The switches may be set according to the following charts if it is known that your equipment will operate normally under such line voltage conditions. Normally, the switches should be left in the down position (this is the factory setting).

K250EI, BK400EI, BK600EI specifications

American Power Conversion (APC) is renowned for its innovative power management solutions, and its uninterruptible power supplies (UPS) are a testament to this commitment. Among their product lineup, the BK600EI, BK400EI, and K250EI models are popular choices designed to provide reliable power protection to various devices and systems.

The BK600EI is a 600VA UPS, ideal for protecting office equipment, personal computers, and networking devices. One of its standout features is the line-interactive technology, which provides voltage regulation during brownouts and surges. This model also supports an LCD display that offers real-time data on battery status, load capacity, and input voltage, enabling users to monitor their power environment easily. Additionally, the BK600EI has a compact design, making it suitable for space-limited areas.

Conversely, the BK400EI is a slightly lower-capacity model, rated at 400VA, making it an excellent option for smaller systems or devices with lower power requirements. Similar to the BK600EI, it employs line-interactive technology, ensuring continuous operation even during power fluctuations. This model is designed with automatic shutdown software that protects devices from data loss during power outages, a critical feature for businesses that rely on information stability and integrity.

The K250EI stands out with its 250VA capacity, catering to entry-level applications. This model is perfect for those needing basic power protection for devices such as routers, modems, or small desktop computers. The K250EI is designed with overload protection, ensuring that devices are safeguarded against electrical surges and overload conditions. The LED indicators provide a quick visual reference for the unit's operational status, reducing user effort in monitoring performance.

All three models share essential characteristics, such as a compact footprint, user-friendly interfaces, and advanced battery management technologies that improve longevity and efficiency. They also come equipped with multiple outlets to ensure users can connect various devices simultaneously. Furthermore, each model is engineered to minimize the environmental impact, boasting energy-efficient designs that contribute to reduced power consumption.

In conclusion, the APC BK600EI, BK400EI, and K250EI UPS models exemplify affordable and effective power management solutions.
