Product Details:

HVG is used to guard the voltage of singlephase low voltage networks. It monitors the voltage level and in case of deviation from the set values (lower and upper limit), it disconnects from the power supply by means of relay (with fixed set delay TR = 2 sec). This delay prevents erroneous response of output relay during the occurrence of parasitic flickers on the voltage curve of the monitored network. In the event of failure the HVG ensures abidance of error state with a fixed set time TH = 300 sec. In-built relay is equipped with a change-over contact 250 VAC/16 A/AC1 which can be used for direct connection of the protected appliance to phase voltage. Models are supplied in a housing suitable for mounting on DIN rail 35 mm (1-pole design). Operating status is indicated by two LED diodes placed on the front panel → Green-normal, Red - undervoltage, Red(blink) - overvoltage.
Note: In-built contact complies with the use for switching category AC1 (non-inductive or low inductive loads such as resistive heaters, etc.). In case of HVG applications in installations for switching of inductive loads (motors, electromagnets, valves, etc.), it is suitable to use the HVG in-built contact to control the contactors with acceptable dimensioned power contacts.

Portable service equipment intended for a quick diagnostics of operation efficiency of SPDs - class III, the device can be also used for a quick orientation control of SPDs condition - class I and II.

Portable service equipment for quick diagnostics and operation ability of SPD - class III (all kinds of HAKEL data, communication and coaxial performance). Due to its friendly maintenance and wide versatility is using this appliance recommended at service and development workplaces.

This Voltage & Frequency Protector is recommended for use in AC parts of photovoltaic systems or other types of AC electrical installations. HUF is equipped with switching contact intended for external contactor control. This contact will operate once the HUF gets connected to monitored system after initialization of its internal electronics. Subsequently, HUF device continuously monitors two basic magnitudes (voltage and frequency) of connected AC power system. In case of their deviation from the preseted values the switch contact will open and consequently the external contactor will disconnect the equipment from the monitored AC power system. In this way, it is possible to disconnect all protected equipment from monitored AC power system immediatelly. HUF 003 is suitable for use in three-phase or in one-phase applications since reconfi guration of measuring mode is made automatically by inbuilt microprocessor. The basic working limits of overvoltage / undervoltage / frequency and basic response time are set by producer. The customer can alternativelly change the presetted basic limits by HUF MONITOR software after PC connecting to RS232 port of HUF

Optional supplementary equipment of TESTER H2 designed for control of data SPD fitted with RJ45 connectors at the input and output (or it can be fitted with RJ12 connector when using connecting reducers).
