Relay 707 L

Product catalog summary

Description: The Relay 707 L is a polarized latching relay designed for capacitive loads up to 140 µF and lamp loads up to 2,500 W. It utilizes the H-armature principle, providing high resistance to shocks and vibrations, and maintains a defined switching position to prevent information loss during power failures. The relay operates with a pulse-driven mechanism, minimizing coil heating, and can be manually set.

Specifications:

Coil Data: Rated voltage ranges from 6 to 48 VDC, with a rated power of 1.5 W and operating power to set at 0.9 W. The pulse to set is 20 ms, and action time is less than 10 ms.
Contact Data: Maximum contact arrangement is 1 a, with contact material AgSnO2. It supports a maximum switching power of 5,000 VA, voltage of 440 VAC, and current of 10 A. Mechanical life is rated at 1 million cycles.
Insulation: Creepage and clearance distance between coil and contact is 8 mm, with a test voltage of 4,000 V eff. Dielectric strength is 12 kV / 1.2 / 50 µs.
General Data: Operates within an ambient temperature range of -25 to +70 °C and weighs 21 g. It conforms to VDE, UL, CSA, SEV, and SEMKO standards.

Electrical Endurance: The relay supports various lamp loads with different endurance cycles, such as incandescent lamps up to 2,500 W and fluorescent lamps up to 2,500 W with parallel compensation.

Standard Windings: The relay features double winding coils with nominal voltages of 6, 12, 24, and 48 VDC, each with specific operating voltage ranges and coil resistances.

Recommendations: The relay is dust-protected, and care should be taken during soldering to prevent flux medium and lead-tin evaporations from entering the relay.

Technical Drawing: A detailed technical drawing is provided for installation and design reference.

Catalog excerpts

Technical Data Relay, polarized latching for capacitive load up to 140 uF Using the H-armature principle the polarised latching relays are noted for their high resistance to shocks and vibrations. They are always in a defined switching-posi- tion and therefore there is no loss of information in case of power failure. The advantage of polarised latching relays is the pulse driven operation of some milliseconds, coil heating can be neglected. Relay can also be set by manual operation. The relays are designed and manufactured in accordance to international Standards of IEC and 61810 part 1/VDE Technical data Coil data Rated voltage 6-48 VDC Test voltage contact - contact open contact coil - contact General data Ambient temperature -25 ...+70 °C
