• ESS mode can provide up to 99% system efficiency, significantly reducing UPS power consumption and

cooling power consumption.

• In ESS mode, UPS built-in filter protection devices can still provide surge protection to ensure high-quality

power output.

• 3C3 HD can intelligently switch between ESS mode and double conversion mode automatically according to

the quality of the power grid. The typical switching time is only 2-4ms.

• In ESS mode, the reliability of key components is further improved and the service life is longer.

3C3 HD 20-200K UPS efficiency is up to 96% at online double conversion mode and 99% at ESS mode.

Smaller size, saving space in

computer room

The 3C3 HD adopts innovative modular design, optimizes the design

and layout of rectifiers, inverters and other components. On the premise

of ensuring reliability, the volume and weight of the product are greatly

reduced, which greatly saves the computer room space and improves the

utilization rate of the computer room. Compared to current mainstream

products in the market, the 3C3 HD saves 50% in footprint space and 90%

in volume.

Safe and reliable. Suitable for various application environments

DUSTPROOF DESIGN

Santak 3C3 HD has a dust filter to isolate dust from the outside of UPS, improving the adaptability to the harsh

environments. At the same time, the internal layout and airflow distribution are optimized, which greatly reduces

the dust accumulation.

• Dust filter complying with American fire protection standard UL94 and dust filter standard UL900.

• Easy to disassemble and clean. Low maintenance cost.

CAPACITORS HEALTH MONITORING

Santak 3C3 HD innovatively adopts a filter capacitor health monitoring

function, through real-time temperature detection of the internal

capacitor, monitors the health status of the capacitor, provides early

warning information before the capacitor is damaged, avoids the

occurrence of failure, and greatly guarantees the stability and reliability of

power for critical loads.

• Use temperature sensors to detect real-time temperature of all input

and output filtering capacitors.

• Fully automatic intelligent judgment of capacitor life, providing warning

information before the expiration of capacitor life to avoid faults.

• The protection measures will be activated as soon as possible in case of

abnormal capacitor faults , avoiding further expansion of faults.

PCBA COATING

Short circuit caused by corrosion of PCBA is one of the important

reasons for failure of UPS, especially in coastal cities. Santak 3C3 HD uses

advanced intelligent PCBA coating technology to further improve the salt

spray and corrosion resistance of the product.

• Full-automatic coating process to avoid manual operation error and

ensure coating precision and consistency.

• Blue-ray detection technology is used to ensure the coating quality.

INTELLIGENT PARALLEL

REDUNDANCY

The Santak 3C3 HD has built-in

synchronous CAN communication,

and no need to install a parallel

card during parallel operation. It

ensures output synchronous and

load balance of each UPS in the

parallel system, and ensures the

reliability and redundancy of the

parallel system.

• Point-to-point control, no

\"master-slave\" dependency

parallel control.

• No traditional load sharing lines.

• Eliminate single point of failure

in the system.

• Fast fault detection and

breakaway technology.

• Reliability is further enhanced.

• The first two-stage charging

mode ensures that the battery is

fully charged.

• The third stage rest mode make

the battery in the state of natural

discharge. UPS detects the

battery voltage in real time, and

automatically starts the charger

to enter a new charging cycle

again when the battery voltage

drops to the setting value.

• Intelligent rest mode can extend

battery life by up to 50%.

SANTAK INTELLIGENT BATTERY MANAGEMENT

3C3 HD adopts Santak intelligent battery management technology. In addition to the traditional two-stage

charging, it also has an intelligent rest mode to avoid the aging effect of the battery due to long-term floating

charge. This technology can also accurately predict the working state of the battery, detect potential discharge

faults in advance and give a warning.
