SEECO motor operators are designed specifically for the
control and remote operation of group operated switches in distribution,
substation and transmission switching applications. Available in a wide
range of motor control voltages, output torques (thrusts) and operating
speeds, SEECO motor operator devices will operate any make or brand of
group operated switch without limitation. SEECO operators can be provided
for either torsional or reciprocating styles of switch operation. A two
speed unit is also available for switches with blade latching mechanisms
requiring normal open and fast slam close.
Our newest generation of operators (type MNM) is the
most advanced and cost effective operator available, providing more user
features and functionality with an automation-ready and maintenance-free
design. MNM operators offer exceptional value by providing features in our
standard units that other manufacturers typically offer as options at
Standard features on all MNM operators include a
galvanized steel mounting bracket, an operator control panel with
local/remote switch, open/close push buttons and local indicating lights,
8 form "c" auxiliary contacts for customer use, DC knife switch, heater
with thermostat control, recirculating fan and temperature data logger, 15
amp GFI receptacle, terminal blocks, door operated interior convenience
light, torque relief knob, swing handle for manual operation, external
coupling mechanism, removable door with lift-off hinges, door hold back,
screened louvre with dust filter, heavy duty stainless steel three point
latch, drawing pocket and an aluminum enclosure.
Power for the operators is provided by either 48 or 125
VDC station service or a 24 VDC integral power supply (batteries and
charger) contained within the main enclosure. For remote switching
applications where station service or 120 VAC source voltage is not
available, a highly reliable solar power supply package can be provided.
Units with the 24 VDC power supply include an advanced battery management
system with "smart" charger, battery testing function with user definable
test cycles and two 12 volt, 33 amp hour batteries as standard features.
MNM operators also provide numerous local and remote
indications of operating status and condition as standard features. Status
indications include switch position (open or closed), door open,
local/remote switch position, DC knife switch position and swing handle
removed. For units with batteries and a charger, additional status
indications include loss of AC alarm and low voltage DC alarm. Optional
status indications include coupling status and motor current draw (switch
maintenance indication). All status indications can be easily checked
locally through LED lights.
For distribution and transmission switching
applications MNM operators are automation-ready and provide an excellent
platform for the integration of an RTU, communication device (radio,
modem, cell phone, pager, etc.), current/voltage sensors and other
automation-related equipment. SEECO operators are compatible with all
RTUís and communication devices irrespective of manufacturer or brand.
Locating these devices within the MNM operator enclosure eliminates the
need for additional customer-supplied enclosures on the pole structure;
this reduces pole clutter, field installation time and cost.
