Albright International HV500AF-13 12Vdc 'Normally Open' solenoid contactor with auxiliary switch, PWM controlled.
- 12 Volts DC single-pole, single-throw (SPST) contactor with flying leads.
- PWM operation is reliant on smooth DC supply.
- These contactors are primarily for use with Direct Current (DC) or Alternating Current (AC) loads via the main stud terminals. The coils are switched with a Direct Current only.
- PWM is not compatible with ramped supply voltages.
- Fitted with a Normally Open (NO) auxiliary switch with white flying leads.
- Initial Operating Wattage: 48W
- Running Wattage: 3W
Applications for Types of HV500 Contactors Include
- Automotive - Vehicle and Charging
- Battery Management Systems
- Power Distribution Units
- Renewable Energy
Dimensions
- Height, including terminals and coil base: 71mm.
- Coil width, including base: 81mm.
About PWM Controlled HV500 Solenoids
This contactor is fitted with a PWM Coil Economiser - allowing for significantly reduced power consumption while maintaining optimum switching capability.
Hermetic Sealing: The Albright HV range is fully hermetically sealed, allowing durability in extreme environments or when operating in potentially hazardous conditions. Please note; hermetic sealing also includes the PWM circuit.
Mounting is through a rotatable bracket which offers 6 angles for orientation. This allows for complete flexibility with the position of main contacts, allowing for customer ease of connection. Recommended panel mounting tightening torque is 2.5Nm to 3Nm.
| Interrupted Current: The opening and closing on load with frequent switching (resulting in increased contact resistance). |
| Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance). |
