Haug has a variety of power supplies or power packs to address each application depending on the critical nature of the specific use. For non-critical applications the standard EN-C power supply is a low cost means to power the ionizing products. The EN-C has two outlets (also called the EN-C2) to handle two ionizing product connections. The EN-C4 has four outlets to handle up to four (4) connections. The EN-C2 and EN-C4 are CSA approved for North and South American Applications. The EN-SL or S-Line power supplies or power packs are CE approved and used where the CE mark is necessary. Variations in the EN-SL or S-Line are the EN-SL LC or S-line LC where and indicating light indicates if there is a problem with the power supply and the EN-SL-RLC or S-line RLC which has a signal socket to connect to a main center to signal fault if it occurs. The EN8 power supply has eight (8) connections for a multiple requirement of ionizers off one power pack and fault indicating light. The EN 70, EN 70 LC and EN 70 RLC has tow pairs of connections which are offset in phase by the second pair of connections to be used in very high speed applications to insure effective static elimination. Like the S-Line they have a version with an indicating fault light (the EN 70 LC), and one with a socket to connect a line to a main board to indicate if any fault occurs (the EN 70 RLC). The Multistat goes even further with four connections and a analog gauge to show the voltage used to assure it is within operating range, as well as a socket to wire into a main board to signal a problem should it occur. A version of the Multistat (or the Multistat-Ex) is for explosion proof static elimination applications with a built-in feature to shut down should the potential exist for a spark to occur.
