SBW
DBW Three-phase
and Single-phase AC Manostats
Purpose：
SBW DBW three-phase and single-phase AC manostats
are high-power regulated power supply characterized
by contact voltage regulating and automatic compensation.
When voltage of electric network fluctuates or load
current shifts, these manostats can output stable voltage
automatically to guarantee failure free operation of
electric appliances.
Application：
Power supply of small-sized factories
Power supply, post and communications of industrial
workshops and departments of large and medium sizes
Supporting important equipment and individual machines
Performance of Three-phase
·Input：Three-phase four-wire system Phase Voltage 175－250V
Line Voltage 304－456V
·Output：Three-phase four-wire system Phase Voltage210－230V
Line Voltage 361－399V
·Leading in and out terminals （phase conductors and
neutral conductor）can bear 50Hz line frequency and 200V
sine voltage of bracket for one minute
·Efficiency：When manostat works under normal power,
the efficiency is higher than 98％.
·Additional waveform distortion of output voltage <1％
Performance of Single-phase
·Input Voltage：176V－264V 130V－260V
·Output Voltage：220V±5％ Line Voltage （can be set）
·Withstand Voltage：2000V, no breakdown within one minute.
·Main Technical Traits：Updated international compensation
techniques are used. Manual and automatic control modes
are available. No guard is needed for regulated voltage
of electric supply; free switch without break; high
precision for voltage regulating; wide range; no waveform
distortion; overvoltage protection; delayed automatic
recovery; automatic switch off delayed failure adjustment;
three-phase imbalance; sound and flash alarm.

Compensation Type Electric Manostats
Instruction：
SJW-WB DJW-WB
single-phase and three-phase series of
high-power full automatic compensation
type manostats embody up-to-date winding
compensation, noncontact switch and microcomputer
control AC voltage regulating technology,
so they are characterized by high efficiency,
energy saving, rapid adjustment, three-phase
automatic balance, no mechanical failure
or abrasion of carbon brush. Moreover,
they have delay function, overlaod protection,
undervoltage alarm and so on.
1. Updated combination winding compensation
technology is used, so there is little
waveform distortion.
2.Onechip control combinations brake tube
is used to switch combinations for proper
compensative regulation. Instant noncontact
adjustment is realized. The instantaneous
overload is high enough to fit for various
loads.
3.SCM is used for subset control. They
have functions of delayed startup, three-phase
automatic balance adjustment, display,
alarm and protection of loss of phase,
overload and failure etc.
