Shiva Amvaj Digital Load Monitor Relay
Shiva Amvaj Digital Load Monitor Relay controls the disruptions caused by current asymmetry and over/under current.It is suited to industrial applications and does not require a CT. the device comes in two models: the 1-60A and 0.5-15A models respective accuracies of 1A and 0.1A.
Features
- Microprocessing unit provides complete protection for three-phase devices
- Current control based on( I2t) curve
- Measures current without requiring a CT and holes for current carrying wire (max 22 mm2)
- Displays current, set values, and error warnings
- Protection against over current, under current, and current asymmetry
- Display:
- Voltage
- Operating hours (conducting current)
- Number of current connect/disconnect times
- Automatic reset can be enabled or disabled
- Ten indicators:
- OL: over current (1-60A or 0.5-15A)
- UL: undercurrent (adjustable down to 1A below OL)
- %A: current asymmetry (7-100%)
- ON: connect/reset delay (0-24 sec)
- OFF: disconnect delay for OL or %A erros (0-10 sec)
- Normal: relay mode(blinking=disconnected/fixed=connected)</li>
- Delay Start: Initial start time (0-120 sec)
- setting UL to zero disables under voltage mode.
- Initial start time indicates the time after relay connection and current conduction during which over current (for initial motor start) is not considered.
