electric transformer, Circuit breaker Unregulated

⒈ over the regulator's own voltage range (to replace a wide range of regulator)

⒉ travel limit switch is bad (replace)

⒊ board is bad Circuit breaker‍ (replace)

⒋ servo motor burned (replacement)

Work trip for no reason

⒈ small total gate capacity selection (replacing the appropriate capacity air switch)

⒉ air switch is bad (electric transformer,‍)

⒊ momentary surge voltage is too high (to replace non-contact high-precision voltage regulator)

Regulators Internal buzzing sounds great

⒈ overload load up (after reduction connected equipment)

⒉ internal debris inside Electric transformer‍ (to remove debris)

Regulators Internal loud creak

⒈ voltage instability (normal)

⒉ Brush surface grime (after removing dirt outage calls)

Regulators can not run automatically

⒈ automatic toggle switch is not turned on (on)

⒉ circuit board failure (electric transformer,‍)

Press the panel no boost or buck buck

(Non-power regulator is no such function)

⒈ servo motor burned (replacement)

⒉ travel limit switch is bad (replace)

⒊ circuit board burned (replacement)

⒋ manual, automatic knob is not open to the manual (open to the manual)

Tips: If the regulator fails, can not be mcb circuit breaker‍ ruled out when they can not stop when the power supply to the back-end equipment; please contact a professional company.
