1. Application

GSA1 series automatic transfer switching equipment is used to shift from the abnormal power supply to in case of one line of abnormal power supply ( normal power supply and standby power supply or normal power supply and the generating power supply), both of which have the rated operational voltage of AC400V, 50Hz, rated current of 10A to 800A , So that reliablity and continuous are ensured . This switch with undervoltage , overvoltage phaes missing, overload and short circuit protection . This swith often used in hospitals, shopping malls, banks, chemical industry, metallurgy , building other importanr sites electricity.

This swith performs the standard of GB/T 14048.11-2002 < < Automatic tansfer switching equipment> >.

Tha category of utilisation and class of this this switch are AC-33iB and CB.

2. Type

 

3. Use scope

The ambient temperature is－5℃～＋40℃ and the average value within 24hours isn' t above +35℃ The relative hunidity ofthe air isn' t avobe 50% at the max , temperature of +40℃, average temperature isn' t avobe +25℃ at the max, hunidity, and the average relative hunidity isn' t avobe 90%, Dew on swith due to temperature alteration should be removed.

The elevation isn tabove 2000m.

Pollution protection: Grade 3 .

4. Main feature

LCD displays: Nameplate pages can be shown, setting parameters pages, running pages, memory pages and so on , each page shows a different function , man and machine can be achieved to dialogue on display and buttons.

Password settiing: setting parameters have password-protected, if changes of parameters that must be set the correct password after amendment.

Setting parameters: under-voltage volue , over-voltage value, conversion time ( t1-t6 )for action can be set free.

Three unite one of the way : type R, type S, type F work in an integrated controller, use- rs may choose work mode of controller at scene.

Error alarm: when normal power and standby power appear undervoltage, overvoltage, phase missing, short-circuit and overload failure, corresponding lights alarm flashing.

Error memory function: it can memory last power error(normal power or standby power ), fault type ( overvoltage , undervoltage, lost voltage, lacking phase), error max voltage value and min voltage value.

Dual-off function: intthe eventof a fire or other emergency situations, normal power supply and standby power supply switch off , two power unable to operate.

Overload and short-circuit protection: see table 3 .
