Features

• Capacitive buffer module bridges short duration voltage drops or load fluctuations.
• For an uninterruptible power supply
• Internal diode between input and output enables operation with a decoupled output.
• Buffer modules can be readily parallel-connected to increase buffer time or load current.
• Potential-free contact for charge condition monitoring
