Blowers Single Phase Failure Relay , Time Delay Undervoltage Relay
LCD Indicating
♦ Descriptions
The single-phase voltage monitoring relay SVR1000/AD220 is
AC/DC supply in Single phase circuit for protect the
overvoltage and undervoltage
Digital screen is easy to check the voltage is normal or not ,
convenience and humanization design
Small size can put in everywhere and lightweight will not be more
pressure for machine
Of course the small contact capacity make it more sensitive for
home type , it will be more quickly when you use it in industry
♦ Features
-- Powered by the measuring circuit
-- Compatible with AC and DC supply
-- Built-in LCD and keypad afford a precise,digital setting
-- Compact modular 43mm housing
-- Adjustable over- and undervoltage threshold
-- Independent adjustable delay time for overvoltage, undervoltage
-- 1 CO & 1NC contacts
-- Fault recording with last 3 faults
♦ Protective Functions
-- Overvoltage
-- Undervoltage
♦ Typical Applications
• Pumps • Fans
• Blowers • Motors
• Compressors
♦ Approvals
• CE • CCC

Parameter Setting Method
Press and hold key MOD for 3 seconds to get into parameter setting interface,then
press MOD to shit to next parameter,press + - to set up the values. Long press+ -
could accelerate increase or decrease.Press RST to exit setting.
Voltage phase-sequence protection for many years (equipment,
refrigeration equipment, crane (passenger and goods) elevators,
control of DC power supply system (Cabinet) screens, precision air
conditioners, room air conditioners, electric hoist, boiler
equipment, laser equipment, parking equipment, cranes, compressors)
and so on using the run.
