Product Description

BL1250U | Battery Backup
Protect desktop computers, workstations, networking devices, and home entertainment systems

Product Overview


A mini-tower UPS with line interactive topology, the CyberPower BL1250U provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The BL1250U uses Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, which extends battery life. AVR is essential in areas where power fluctuations occur frequently.

Two USB Type-A charge ports power portable devices such as mobile phones and tablets, even during a utility power failure. The BL1250U comes with a three-year warranty (including coverage of batteries) and a $400,000 Connected Equipment Guarantee.

  • Battery Backup
    Supplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown.
  • Surge Protection
    Diverts excess voltage away from sensitive electronic equipment during an AC power surge or power spike to prevent damage.
  • Automatic Voltage Regulation (AVR)
    AVR increases the AC power and maintains a safe voltage level without switching to battery mode and conserving battery life.
  • Multifunction LCD Panel
    Displays immediate, detailed information on the battery backup and power conditions, alerting users to potential problems before they can affect critical equipment and cause downtime.
  • USB Charge Ports
    Rapidly charge and power USB devices.
  • Widely Spaced Outlets
    The widely-spaced outlets allow you to conveniently add transformer-sized plugs without blocking other outlets.
  • Data Line Protection
    Prevents power surges that travel through Ethernet lines from causing damage to electronics.
  • PowerPanel® Personal Software
    Provides a user-friendly dashboard interface for controlling and monitoring the UPS. Free software download available. See the Resources tab.
  • Ultra Quiet Design
    Minimizes noise during operation for a quieter work environment.
  • Simulated Sine Wave Output
    Provides a manufactured waveform output to supply cost-effective battery backup power for equipment that does not require sine wave output.
  • ENERGY STAR
    This model is an ENERGY STAR® certified Uninterruptible Power Supply (UPS) system. ENERGY STAR is the trusted, government-backed symbol for energy-efficient products and practices that help save money and protect the environment.
  • GreenPower UPS™ Bypass
    A patented design that allows utility power to bypass the UPS transformer, when AC power is stable, which reduces energy consumption, noise, and heat buildup.
  • Three-Year Warranty
    CyberPower will repair or replace a defective UPS system (including batteries) within three years of the purchase date.
  • Connected Equipment Guarantee
    CyberPower will repair or replace properly connected equipment if it is damaged by a power surge.

GreenPower UPS Technology: Bypass Design

GreenPower UPS™ Technology from CyberPower improves operating efficiency, reduce heat generation, and consume less power than conventional UPS models.

Our patented Bypass Design allows current to bypass the transformer and automatic voltage regulation (AVR) when utility power is normal, thus reducing energy consumption and associated costs. Because utility power functions normally most of the time, the bypass design allows for substantial energy savings. This technology also reduces heat generation, an important factor in decreasing operating costs.


Transformers and Transformer Outlets

A transformer converts alternating current line voltage to a higher value or a lower value. Transformers rely upon electromagnetic induction, the process which occurs when the alternating current within a circuit generates current in a nearby circuit.

Transformers vary in design and size, as well as using different amounts of current. Small transformers plug into a wall outlet and create low direct current voltages which are used by common electronic devices. Transformer outlets are more widely spaced than other outlets to accommodate transformer block adapters or other adapters that are large in size. Transformer outlets can be used to connect any appropriate device to a surge protector.


Automatic Voltage Regulation

Automatic Voltage Regulation (AVR) in line interactive UPS systems stabilizes the incoming AC signal to maintain output power at a nominal 120 volts by controlling high and low voltages without resorting to battery power. This significantly increases battery life and lessens the likelihood of data loss, memory freezes, and system crashes.

How AVR Works in a Line Interactive UPS

A line interactive UPS includes an AVR autotransformer a special type of transformer designed to switch between powered coils of wire in response to variances in utility power input, thereby increasing or decreasing the magnetic field and the resulting output voltage to connected equipment.

This type of UPS tolerates undervoltage brownouts and overvoltage surges without consuming backup battery power by automatically selecting different power taps on the AVR autotransformer. During normal operation, incoming AC power bypasses the autotransformer (where voltage highs and lows are controlled) while also charging the battery. When the incoming voltage falls below the AVR range, the UPS switches to battery backup, and the DC-AC inverter circuitry is engaged. Power will continue to be supplied by the battery-inverter circuit until incoming voltage returns to the range manageable by the AVR.

What does the Wiring-Fault Indicator light mean?

What is the Wiring-Fault Indicator?

The LED indicator will illuminate red to warn the user that a wiring problem exists, such as bad ground, missing ground or reversed wiring.

What is bad ground?

If your CyberPower unit shorts out or there is a surge/spike in power, it can become a fire hazard by not properly grounding the wire to the earth ground that is connected to your house.

What is missing ground?

A missing ground can cause electrical shock.

What is reversed wiring?

This is caused by the hot and neutral wires being reversed in the wall outlet.

Solutions to try and diagnose the problem:

Try connecting the CyberPower unit into another outlet. If the wiring-fault light indicator is still illuminated contact an electrician to correct the problem with the faulty wall outlet.

What are the red reset buttons on the back of my UPS for?

Those are circuit breakers. If one of the circuits were to be tripped, that button would be sticking out significantly farther than normal and would need to be pushed back in to reset the circuit.

What types of equipment are NOT allowed to be plugged into the UPS?

Any device which exceeds the unit’s VA/Watt rating should not be plugged into the outlets. High drain devices, medical equipment, and aquatic equipment also void the unit’s warranty. Below is a list of other devices that also void the warranty.

  • Laser printers
  • Space heaters
  • Copiers
  • Paper shredders
  • Vacuums
  • Curling irons

Where is the serial number located on the UPS?

Your CyberPower product serial number (S/N) is located on a small white rectangle label located on the bottom or back panel of your UPS system. The serial number will appear in various places depending on the product you are referencing.

SX650U Serial Number

The label will have a barcode with a 12-character code right below it–this is your serial number. It may include your product’s model number and the words Made in China.

What is the difference between the Battery/Surge outlets and the Surge outlets?

Many CyberPower UPS units have two sets of outlets. One set is labeled “Battery/Surge” and one set is labeled “Surge”. The outlets labeled “Battery/Surge” are the outlets that will receive battery power during a power failure. You should plug your computer and monitor into these outlets and any externally powered critical data storage device.

Items such as printers, speakers, scanners, and faxes should be plugged into the outlets labeled “Surge.” These outlets are intended for low priority electronics that are not essential to the PC’s main operation.
