NOVAR 1106 / 1114 / 1206 / 1214 NOVAR 1xxx / S400 NOVAR ...

NOVAR 1xxx EPM Elektropřístroj s. r. o.
Besides the power factor capacitors, it is possible to connect power factor chokes (power system
decompensation). Any output can be set as fixed, the two highest outputs can also be used to connect
the cooling or heating circuits.
The controllers come in two basic designs with different numbers of outputs: NOVAR1106/1206 with
six output relays and NOVAR1114/1214 with fourteen output relays. The NOVAR12xx controllers
have, as opposed to the 11xx line, an additional voltage measurement input and a second metering
rate input.
Both types of controller have an Alarm relay output that can be set to indicate non-standard
conditions, such as undercurrent, overcurrent, measurement voltage failure, overvoltage, harmonic
distortion preset threshold exceeded, overcompensation or undercompensation, section limit
connection rate exceeded, section outage, backfeed condition (power export) or overheating.
All types of the controller can be ordered in a version featuring an optional galvanic-insulated RS-232
or RS-485 communication interface. All values measured can be then monitored and the controller’s
parameters set using a remote computer.
1.3 NOVAR Controller Version “/S400”
Controllers of version ―/S400‖ ( model marking example : NOVAR-1114/S400) diifer from standard
version of the NOVAR-1106 / NOVAR-1114 / NOVAR-1206 / NOVAR-1214 models in following
aspects :
increased maximum power supply voltage up to 500 V, both AC and DC
relays’ common contacts insulated, connected to additional terminals
The ―/S400‖-version instruments can be used at insulated networks (without neutral wire). The other
features are identical to those of standard version.
1.4 NOVAR1005 / 1007
These models are simplified versions of the NOVAR1106 / 1114 models. They are built in smaller box
and designed for less demanding applications. NOVAR1005 features 6 output relays, NOVAR1007
features 8 output relays.
1.41.5 NOVAR1312
NOVAR1312 is designed to provide rapid compensation using thyristor switches. It differs from
NOVAR1214 in the two following principal aspects:
outputs 1 through 12 are transistor-driven
control speed for these outputs can be set up to 25 interventions a second
NOVAR1312 specific features are described in a separate chapter. The other features are identical to
those of NOVAR1214.
