  • Maximum load current is 16A (4,0kW)
  • Synchronous control of the relay - closure relay contacts is carried out by passing mains voltage through a zero
  • Setting the time switch-on after the excess power from the 10s up to 6min
  • Two-threshold protection from overvoltage and undervoltage
  • Built-in varistor protection from pulse spikes mains voltage
  • Keeps working capacity at a supply voltage up to 400V
  • Setting the power limit from 0,1 to 2,5kW
 
PURPOSE OF THE DEVICE
 Power limiter OM-16 provides the control value of the maximum power in single-phase nets and switches off the supply of electricity from the consumer in case of excess power consumption than the set value, and also protects the equipment connected to it (in the flat, office and so on.) from the damaging action of pulsed power surges caused by electromagnetic pulses of close lightning strikes or actuation closely spaced and connected to the same net of electric motors, magnetic starters or electromagnets, and also switches off equipment, when mains voltage is leaving an allowable ranges (<160V or> 265V), thereby preventing equipment damage and possible fire, followed by a fire. Can be used in any net configuration: TN-C, TN-S, TN-C-S, TT.
 
 WARNING: The device does not replace other protection devices (automatic circuit breakers, surge arresters, RCDs, etc.).
 
DESIGN OF THE DEVICE
 Device is mounting on a DIN rail width 35mm (GOST R IEC 60715-2003) with a unified front connection wires power and switched circuits. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are: red LED "ALARM I", red LED "ALARM U", yellow indicator of ON of relay contact, green LED "NORMAL", button "TEST" of manual control, rotary switch "RESTART TIME". On the left side of the case is the rotary switch "Power P, kW (Current, Amperes)". After setting required power level limit the authorized representative of power sales organizations must remove the knob and covering the hole with a filling disposable nameplates (supplied in kit), beforehand making it all the necessary data.
 
OPERATION OF THE DEVICE
 When the supply voltage is turned on, device controlls the value of voltage and the value of consumed by the load current, calculates the acting value of the power consumption. If the power consumption does not exceed the set valuelights up green indicator "NORMAL". With long-term increase in the power consumption more than the set value, the device disconnects the load at the time set by the user. During a counting of this time lights the red LED  "ALARM . Time OFF at overload is fixed. Restart time is set by the consumer by switch on the front panel.
 After turns off a load starts the set counting of time. During counting of this time flashes the red LED "ALARM I". On expiry this time, the load is connected, if the power of the exceeding tendency kept, then begins time off - 10s. After five cycles of turn on and off the load, the set time on is automatically increased to 6m, which eliminates some of the load connection.
 In the device is provided auxiliary mode - voltage control. When the supply voltage, device can stand ready time 5s while the indication is not working. If the voltage is in appropriate ranges the green LED "NORMAL" start to flash pointing to the counting delay time on 10s, then the load is connected to the net of supply voltage and lights up an yellow indicator.
 If the supply voltage reaches the upper off threshold (265V), the device disconnects the load through the 0,2s and the red LED "ALARM U" turns on, if the supply voltage reaches the lower off threshold (160V), the device disconnects the load through 10s, during the counting time is flashing red LED "ALARM U". After switching off the load the yellow LED turns off, red LED "ALARM U" sometimes goes out indicating at a low voltage power supply net. When restoring the supplying net, device connects load through the 10s, during the counting time flashes the green indicator "NORMAL". When appears in a net powerful pulses of voltage built-in varistor shunts them to the value of safe equipment.
 The user can by himself connect and disconnect the load manually by pressing the "TEST" button. When disconnecting the load by button "TEST" indicators "NORMAL" and "ALARM U" alternately are flashing red and green colors appropriate. The device remains switched off as well after removal and supply voltage. Turn on a load can only by re-pressing the "TEST" button.
 
 WARNING: Do not use the manual mode for emergency net status. When you try to manually activate the emergency mode, the device does not allow to apply power to the load. At connecting a device should be considered cross-section of current-carrying wires.
