ZBW-YL Intelligent Brushless AC Voltage Optimizer for Medical Equipment

ZBW series non contact brushless Thyristor(SCR) voltage stabilizer. This is the third and latest generation of stabilizer, which  is  designed with electronic &  microprocessor  latest technology , static solid circuit with  isolation transformer, with features of no relays, no moving parts, non-contact, brushless, etc. It is  mainly used for energy saving purpose and sensitive expensive equipment, like Medical Equipment.
1. Product Introduction
ZBW voltage optimizer is highly beneficial when the electricity supply to the site is at a higher or lower voltage level than actual needed.
This system stabilizes the input voltage and generates a reliable output voltage to the residential, commercial or industrial site.Therefore, it can protect the load equipment, save energy and reduce electricity bill by decreasing power consumption.
2. Basic Parts
Cabinet (IP 20 for indoor use),Lock and Latch
LCD Display Panel: language can be Chinese, English, Russian,etc
Termination: 3 phase 4 wires +PE(grounding wire)
Main Switch, AC contactor,Cables/Busbar,Insulation tape
PCB main board, Drive board, SCR, Cover,fuse, control transformer
Compensation transformer: 5v/10v/20v(each phase 1 pc)
Other parts unlisted
3. Extra Parts and Function ( Optional )
Cabinet IP grade (can be custom bulit to IP 54 for outdoor use)
Surge arrester inside to against the spikes(3P 20/40KA)
Indicators: Regulation/Bypass/Over voltage/ Under voltage/ Overload/ Start/ Emergency Stop, etc
Harmonics filter to remove site harmonics
Temperature meter to show the temp. of the cabinet and inside components of the stabilizer
Power factor correction unit can be also combined to improve the site PF (eg. from 0.65 to 0.95)
Manual bypass-install a bypass switch ( or call isolator, it has 3 positions: regulation, stop, bypass) inside in case ( for safety reason)
Intelligent and digital meter for input and output: Show L1-L2-L3 electrical parameters comprehensively (A,V,KW,KVA,Hz,var,KWh,etc), output voltage(per line) can be independently 'fine tuned' from within front of cabinet
Online/On-load 'Real Time' internet monitoring of power distribution system via RS-485 or RS-232 communication port via a web accessible Accuvin 11 high precision multi-function data logger

5. Features&Benefits
Non-Contact/Brushless Design
No relays, No moving parts
High accuracy and fast response time
Independent regulate on each phase
Solid state high speed switching (microseconds) Silicon Controlled Rectifiers (SCR')
to suppress harmonics and facilitate the balancing of loads
Fail-safe Electronic by-pass( or call auto bypass), PCB can automatically detect the fault, then go to bypass
High Purity electronically refined first second, third wingdings
Cooling: With fan or without fan acceptable
98% typical efficiency with loading from 15%-100%
All power passes through the voltage optimizer, which is connected downstream of the main switch and metering system of the main switchboard
