ENHANCE ENVIRONMENTAL ADAPTABILITY
Anti-Corrosion Production
PCBA corrosion is one of the
key reasons leading to UPS
components failure, especially
in coastal areas. SANTAK
applies advanced PCBA coating
technology, offering customers
an excellent anti-corrosion
performance.
Optimized Programming
? According to the system
design and air distribution,
we directly program on the
equipment to achieve ondemand spraying, meanwhile
considering the possible salt
spray and dust accumulation
probability.
Automatic Coating Process
? Automatic coating
technology adopted, the
coating precision and
consistency is highly
improved, comparing with
manual coating technology.
Blue-ray Detection
Assisted with blue-ray
detection technology, PCBA
coating quality is significantly
improved.

Dustproof Design
3C3 PRO offers standard
air filter kits, which prevent
the dust out of the UPS and
improves the environmental
adaptability. The filtration kit
meets with
? Easy disassemble and clean,
low maintenance cost;
? Flame resistant;
In additional, the internal
design of 3C3 PRO optimizes
the internal air flow distribution,
which significantly decreases
the dust deposition.
SANTAK INTELLIGENT BATTERY MANAGEMENT TECHNOLOGY
3C3 PRO adopts the advanced 3-stage charging technology. In
the first stage, it charges the battery up to 90% capacity with high
current. In the second stage, it charges the battery to 100% capacity
with constant voltage. In the third stage, it stays in rest mode. The
3-stage charging method can extend the battery life cycle avoiding
long-time floating charge issues. SANTAK intelligent battery
management technology can accurately forecast battery working
mode and remind your customers of potential malfunction.
3C3 PRO supports flexible battery quantity configuration.
Customers possess flexibility to choose different battery capacity
and quantity in the backup solution. Even in the on-run mode,
the battery quantity configuration can be quickly adjusted to
disassemble the malfunctioning battery, while the whole UPS
system can guarantee a constant power supply.
LEADING PARALLEL
TECHNOLOGY
3C3 PRO is embedded with
internal parallel kits powering
by high reliability CAN bus.
With better output voltage
regulation, perfect load sharing
and active protection, 3C3
PRO assure the reliability and
redundancy of the paralleling
power system. 3C3 PRO offers
more excellent performance in
paralleling and improves the
output accuracy. STK CASTLE BATTERIES
——Maintenance-free Sealed Lead-acid UPS Batteries
CASTLE C12V series batteries are being designed with more
focusing on compatibility with SANTAK UPS and system. Compare
to other batteries in the market, CASTLE C12V series batteries
can provide longer float charging life time and more powerful
discharging characteristics. It is an ideal product for SANTAK UPS
backup application.
