Analogue instruments Bidirectional protection wattmeters Analogue indicator to measure three-phase current Electronic instrument on the front panel Input circuit overloads and inverse power. The instrument is composed of a power converter with an analogue output connected to the needle indicator with 2 relays. The unit measures Current measurement range Current overload and indicates the system's power constantly (measurement in 4 quadrants), sending an Auxiliary power supply trip values. The alarm is indicated by activat- ing the output relays. The two LEDS on the front panel can be used to view the status of Consumption Nominal value in DC Consumption Ambient conditions Operating temperature Limit temperature Build features Overload protection Trip point adjustable between 0 and 100% of the scale base power Hysteresis adjustable between 1 and 50% Front panel Delay adjustable between 0 and 30 s Inverse power protection. With various alarm condition is met, the relay is activated generators connected in parallel, one can start consuming power and working as a is not shut down (even when the alarm con- motor, under determined situations ("motori- ditions disappear) zation"). The relay is activated when the circumstances are met. is the same as when the alarm is triggered. The protection system has the following is shut down, the unit sends an alarm. 0 and 20% of the scale base power interlocking (latch), on demand. Delay is adjustable between 0 and 30 s.
