Description

RNPP-312 has been designed:

for monitoring the permissible voltage level;
for monitoring the correct alternation and absence of sticking of phases;
for monitoring the full-phase and symmetry of the mains voltage (phase imbalance);
to disconnect the load in case of improper mains voltage and neutral failure;
for monitoring the quality of the mains voltage after switching off the load and automatically turning it on after restoring the voltage parameters;
to indicate the failure in the event of emergency situation and the presence of voltage in each phase.

The device provides the possibility of adjusting the parameters (voltage threshold, time of automatic reclosing and time delay of protection operation), selection of the voltage of the monitored mains (400 V or 415 V) and a set of protective functions. After restoring the voltage parameters of the mains, the device enables again the load after the reclosing time.

RNPP-312 can be operated in the following modes:

“Minimum and maximum voltage control”;
“Minimum voltage control”;
“Maximum voltage control”;
“Phases presence control” (Single Phasing);
“Control of incorrect phase sequence;
“Presence of phase sticking” (short circuit);
“Phase imbalance/assymetry control”.

Protections can be turned ON/OFF through built-in DIP switch.

The failure is displayed in order of priority:

1 – Phase failure or voltage drop below 100 V (highest priority);

2 – Phase sequence;

3 – Minimum and maximum voltage;

4– Phase imbalance.

Notes: * – When the input voltage drops below U_min, the fixed operation time of the device is 12 seconds, if the switches U_max and U_min are in the “ON” position. With any other combination of switches U_max and U_min, the device will operate after the delay time set by the User with Т_off(sec) control. If during this time (12 seconds) the mains parameters change, for example, at the maximum voltage, the device will operate at the smallest of the periods – after the delay time specified by the User, or after the time remaining of 12 seconds. ** – When working in “Maximum Voltage Control” mode, the ready time is 0.3 seconds.
