Introduction


These Swiss sinewave inverters are powerful and reliable enabling any 230Vac equipment (up to the nominal power of the selected inverter) to be operated from a battery. They deliver high output rates with top efficiency whilst having a low standby power draw.

They use advanced technology with processor control, toroidal transformer and MOSFET power stage to give a harmonic true sine wave 230Vac output with power equal to that of the grid. All standard appliances including sensitive equipment such as computers, radio, audio and satellite equipment can be powered without interference.

The AJ series inverters are ideal for smaller applications and include battery cables and AC output cable. Larger SI units have high overload capability (up to 300%) so even big motors and fridges can be started.  Battery cables are included, AC output via terminal rail.

Specifications (for AJ & SI Series)

Figures in brackets refer to 24 V units.
  • Input Voltage: 10.5-16.0 VDC (21-32 VDC)
  • Output Voltage: 230 Vac (+/- 5%)
  • Output Frequency: 50Hz +/- 0.5%, true sine wave
  • Power draw in standby/sleep mode: < 1W(not J200)
  • Load sensing: 1W to 20W (adjustable)
  • Overload Capability: max. 250% (max 300%)
  • Max. Efficiency: approx. 93%

Protection
  • Low Battery
  • High Battery
  • High and Low Output Voltage
  • Short Circuit
  • Over-temperature
The units automatically shut down if any of the above occur, then the inverter tries to restart three times. If the fault is not removed the inverters switch off. LED indicators show the fault condition and re-start is then by reset switch.

Compact Series Inverter/Chargers


Studer Compact SeriesThis range of combined sinewave inverters/battery chargers from  are powerful, efficient & reliable. They  use advanced technology with microprocessor control, torodial transformer and MOSFET power stage to give a harmonic true sinewave 230Vac output with power quality equal to the grid.    
Clean sinewave output enables all standard appliances including sensitive equipment such as computers, radio, audio and satellite equipment can be powered without interference.  They have high overload capability, so even big motors and fridges can started, combined with low standby power draw for constant connection.  When supplied with generator or grid power they operate as powerful battery chargers making them ideal for use in back-up power or generator systems.  They are extremely quiet and easy to use with fully automatic functions.

  • Input Voltage: 9.5-16.0 ; 19-32 ; 38-64 VDC)
  • Output Voltage: 230 Vac (+/- 10%)
  • Output Frequency: 50Hz +/- 0.5%, true sinewave
  • Power draw in standby/sleep mode: < 1.5W.
  • Load sensing: 1 to 25W (adjustable)
  • Overload Capability: max. 250% max 300%
  • Max. Efficiency: approx. 95%
  • Warranty: Two years.
Protection
  • Low Battery
  • Overload
  • Reverse Polarity
  • Short Circuit
  • Over-temperature
The units automatically shut down if any of the above occur, In the event of an overload the inverter tries to restart four times. If the fault is not removed the inverters switch off.  LED indicators show the fault condition and re-start is then by on/off switch.  In the event of low battery or over-temperature the inverters switch off and wait until the battery is recharged or inverter cooled down before automatically restarting.

Three types of inverters are included in the range with different models for different battery voltages.

Features of Compact Series


Inverters
Extremely quiet and clean sinewave output.  Powerful, reliable and efficient.

Transfer System
When the Compact is connected to an AC source such as grid or generator if changes the load to the AC source (15A transfer relay).  If AC power fails it switches back to inverter.  Switching time is <20ms.

Battery Charger
Built-in powerful  adjustable 4 stage battery chargers are deigned to charge the batteries quickly and completely. For vented or gel type batteries.

Relay Contacts
Includes a 16A voltage free contact.  This can be programmed according to battery levels to operate alarms, disconnect and re-connect loads or provide a signal to start and stop a generator.

Standby
Standby (sleep) mode ensures that minimum energy is needed when all loads are switched off.

Display
An easy and comprehensive LED display unit at the front of the compact gives a visual indication of it's operating mode.  LED bar graphs show power supplied by the inverter or battery charge current, output & input status indicators, alarm LED's & audible alarm.  This display unit is available as an optional remote control supplied with 25m cable.
