Product Details

Camax are now supplying the Hobut Voltage Protection Relay suitable for Single or Three phase systems housed in a 3 DIN-Rail Module (55mm x 112mm or 100 x 112mm).

Used in applications such as mains failure, regulation of power supplies and to protect voltage sensitive equipment. Under, over and combined over/under units are available. The relay operates when the externally adjustable trip point is reached.

An external differential control is provided with adjustment 1-15%. The differential ensures that the parameter being measured returns to % set above or below (depending on whether it is an under or over unit) the trip point before the relay returns to its original state.

As is universal with all the M200 relays, on over units the relay energises when the input signal exceeds the trip point. On under units the relay de-energises when the input signal exceeds the trip point. A red LED indicates the state of the relay whilst a green LED indicates the condition of the power supply.

M200 Models:

• M200-V1U: Single Phase under Voltage
• M200-V1O: Single Phase over Voltage
• M200-V1C: Single Phase combined Voltage
• M200-V33U: 3 Phase 3 Wire under Voltage
• M200-V33O: 3 Phase 3 Wire over Voltage
• M200-V33C: 3 Phase 3 Wire combined Voltage
• M200-V34U: 3 Phase 4 Wire under Voltage
• M200-V34O: 3 Phase 4 Wire over Voltage
• M200-V34C: 3 Phase 4 Wire combined Voltage
