HOMA for Power frequency switching
In this field switches are used to switch on power on load with high frequencies to trigger a signal. This method can be used to switch on or off street lamps or readers for off peak electricity (ripple control systems).
Power frequency switching. Products
For over 60 Years
HOMA switches are being built into different applications for more than 60 years and have been supplied to more than 100 countries. Due to the worldwide experience of HOMA, many national and international norms can be fullfield and have conducted a vast number of type tests for our products. We equip our switches with coils that can be operated worldwide with 60V to 480V AC/DC. The worldwide distribution network ensures minimal downtimes in case of a break down. HOMA is known for short delivery times and due to its modular design, switches can be assembled and delivered within 24 hours.
Air-break contactors and combinations of switches to deal with normal to complicated switching activities for all types of electrical loads.
Sliding contacts, air-break contactors and air- or water-cooled high current switches for galvanic interruption of circuits without a control current for technical or safety reasons.
Different types of commutators to select different sources or for an alternative supply of the electrical load circuit.
Commutators and pole-reversal contactor including associated control systems, reversing contactors etc. for process-related reversion of the electrical current or rotational direction; braking contactors for switchoff for drives that simultaneously trigger dynamic braking systems.
Starting contactor / rotor-short circuit contactor, as well as starting coupling contactor / cascade coupling contactor for large machinery in association with subsynchronous static converter systems cascade; capacitor contactors for balancing or compensating inductive electrical loads. Starting, damping and discharge resistors.
HOMA Bar mounted Contactors
In HOMA Bar mounted Contactors current-carrying components are organized on the basis of a main frame construction. All required modules are arranged on top of a single frame (bar), for example: Magnet system, Terminal plate for power circuit, Switch locking system and Movable contacts. The two examples below (G500 / HAT-2W) illustrate the construction.
High Current Cables
95mm² to 8.000mm². Air- and watercooled.
HOMA offers engineering and fabrication of copper tube systems.
