Pfannenberg FLZ 530FLZ 530 0..+60°C UL0..+60°C Thermostat and hygrostat

Thermostats are used as temperature controllers for managing filter fans or cabinet heaters. They are available as normally open/normally closed and changeover types. When combined with cabinet heaters, they can ensure, especially in outdoor applications, that the cabinet is 'artificially' dehumidified in addition to temperature control. This means that the temperature is maintained above the dew point, preventing water from condensing out of the air and causing short circuits due to condensation. The combination with filter fans offers additional savings in energy, materials, and time, resulting in a better environmental balance and increased safety in the production process through reduced energy consumption and improved efficiency of the filter fans.

The series of twin thermostats combines two thermostats in all combinations for complex switching tasks.

• FLZ520 as a normally open contact with a snap action: suitable for controlling heaters, switching temperature difference < 7 K, switching point tolerance +/- 4 K, adjustable range 0 °C to 60 °C.
• FLZ510: Changeover switch with snap action.
• FLZ520: Normally open contact with snap action (suitable for controlling heaters).
• FLZ530: Normally closed contact with snap action (suitable for controlling fans).
• FLZ541: Normally open and normally closed contacts in one housing.
• FLZ542: Two normally open contacts in one housing.
• FLZ543: Two normally closed contacts in one housing.

The advantages of the series at a glance:

• Suitable for all applications in the industry.
• No influence from electromagnetic radiation, as a mechanically switching contact is used.
• Extends the service life of heaters and fans.
• Optimized energy consumption for heaters and filter fans.
• Easy mounting on DIN rails.
• Electrical connection via screw terminals.
• IP 20 protection for installation inside the cabinet.
• Approvals: cURus, EAC, CSA.
