Minivar Electronic Control Panel

MINIVAR is a range of compact control panels designed for the control and protection of 1 electric pump or electric motor three phase with ABB FREQUENCY INVERTER. Designed and constructed with ABB components, these panels offer reliability and versatility to meet user demands thanks to the numerous compatible accessories available.

• Power supply 3 ~ 50/60Hz 400V±10% - output  3 ~ 400V
• Power supply 3 ~ 50/60Hz 230V±10% - output  3 ~ 230V
• Power supply 1 ~ 50/60Hz 230V±10% - output  3 ~ 230V;
• Auxiliaries contacts and circuits in low voltage
• Normally open contact for start with selector in “Manual” position
• Normally open contact for minimum level/pressure  contact
• Analog input  4-20mA (0-10V on request)
• Selector for Auto-Off-Manual operation (MANUAL stable)
• Frequency inverter with ventilation, LCD, “pid” regulation and connection for RS232/485
• Auxiliaries and motor protection fuses
• Forced ventilation kit
• Enclosure in ABS, IP54
• Ambient temperature: -5/+40 °C
• Relative humidity 50% at 40 °C (not condensed)

The user must have suitable characteristics for inverter application

Earthleakage for mains supply protection must be “A” type (for unidirectional pulsing current with continuous component and for alternate current) protected against sudden release of current with the possibility to select the intervention threshold (recommended 300mA) and the time of intervention at the release (suggested 0,5 sec.)

The expansion vessel is suggested for an exact reading of the pressure, it must be pre-charged at a 30% lower pressure than the working pressure of the system and installed close to the pressure sensor.
