MBE 200/2,0 R2 electrical heater battery

- the cabinet is made of galvanized sheet metal, contains a terminal block, internal installation and a heating power regulator including a power element cooler
- the heating rods are made of stainless steel
- it is equipped with two thermostats, a working thermostat (60 °C) and a safety thermostat (switches off at 120 °C)
- the reset button for the safety thermostat is located on the cabinet, during installation it is necessary to position the heater with regard to the inspection activity
- continuous regulation is carried out by supplying the control voltage with the range of 0-10 V depending on the control deviation or by the built-in temperature regulator
- the heater is equipped with its own temperature regulator with inputs for TGBK sensors
- the regulator allows connection with the Unireg^® control unit, or with a complete Digireg^®

Technical parameters

- control voltage 0 to 10 V DC
- current draw at 10 V control voltage up to 10 mA
- control voltage range for 0-100 % of heater output is approx. 1.9 to 9.6 V
- heat loss at heat sinks max. 0.6 % of heater output (more details on request)
- operating temperature on heaters (at ambient temperature of 40 °C) is up to 85 °C
- maximum temperature on heaters with electronic limitation in case of insufficient cooling up to 100 °C
- heater switching period approx. 20 s
- control circuit is galvanically isolated from mains voltage, maintaining conditions for SELV circuits
- for control systems, which cannot supply control voltage with 10 mA current, PS-21 converter is available
- protection IP43
- they are mounted behind the fan in the direction of air flow, approx. 1 m of pipe must be inserted between the fan and the heater
- when the fans are switched off, the dampers in the system may be closed only after the bars have cooled down, otherwise there is a risk of damage to the heater and other equipment.
- Caution! The electric heater must have a minimum speed through the heating coils of 1.5 m/s to maintain proper operation. Failure to maintain this speed will cause the heating coils to overheat and disable the heater's thermal protection. This significantly reduces the life of the heating coils.

Warning

When shutting down the HVAC system, a fan run of at least 2 minutes must be provided to cool the heating coils. Failure to do so may damage the heater and other equipment."
