Features

• Monitoring of battery voltage 12V, 24V, 48V or 60V
• Current demand max. 14mA (24mA 12V type) with activated relay
• Output 1 relay SPDT 250V AC / 2A
• Alarm function undervoltage / overvoltage
• Switching hysteresis adjustable 2 ... 16%
• Time delay in 2 ranges adjustable (1 ... 60s or 5 ... 300s)
• Measuring voltage = supply voltage
• 2 LED´s for setpoint and power

The BW 500 was designed for monitoring of battery voltages. Undervoltage or overvoltage can be selected.

• Undervoltage : The relay switches off, if the voltage falls under the limit value and if the delay time ran off.
  If the voltage exceeds the limit value+hysteresis, the relay will be activated
• Overvoltage : The relay switches on, if the voltage exceeds the limit value and if the delay time ran off.
  If the voltage falls under the limit value-hysteresis, the relay will be deactivated.
