Lanberg AK-1505-S Thermostat Grey

Lanberg AK-1505-S closing thermostat is a compact temperature control device designed for cabinets and racks used with servers, backup power systems, monitoring, CCTV and alarm equipment. The device uses a thermobimetal sensor and a normally open (NO) fast-acting contact that closes when a preset temperature is exceeded, supplying power to cooling equipment or airflow support products. The grey ABS housing has UL 94 V-0 flammability rating. The thermostat operates at up to 250 V with a maximum switching current of 10 A and standby power consumption of 30 W. Its compact dimensions and multiple mounting options make it suitable for various installations in electrical and server enclosures.

Advantages

The AK-1505-S provides simple, mechanical temperature control without the need for software, reducing unnecessary fan operation and extending component life. Its fast-acting normally open contact ensures immediate activation of connected cooling devices when the set temperature is exceeded. The housing is made from flame-retardant ABS material certified to UL 94 V-0, minimising fire risk inside cabinets. Two mounting options (DIN 35 mm rail clips and a removable flat powder-coated mounting ear compatible with rack mounting) increase flexibility during installation. The product comes with a set of accessories to simplify installation.

• Server racks and network cabinets
• UPS and power distribution cabinets

How to use

Install the AK-1505-S in a cabinet or rack using either the built-in DIN 35 mm rail clips or the removable flat mounting ear; the ear can be positioned left or right and flipped if needed to fit available space. Connect the thermostat’s switching contact in series with the power supply to the cooling device or fan so that the contact closes to supply power when the thermostat reaches the set temperature. Adjust the temperature setting on the thermostat to the desired trigger point. When ambient temperature rises above the set point, the thermobimetal sensor will deform, closing the contact and powering the cooling equipment; the contact reopens when temperature falls below the reset point.

Recommendations

For reliable operation, mount the thermostat where it senses representative cabinet temperature and away from direct air streams from fans; ensure wiring and connected loads do not exceed the specified 10 A switching current and 250 V rating. Use the supplied accessories for secure attachment and follow local electrical safety regulations during installation.
