OVER VOLTAGE PROTECTION

Overvoltage Protection for 24 V Power Supplies

** Specifications

AC Input:

.

* 100/120/220/240 VAC +10%, -13%. 47-63 Hz. Tolerance for 230 VAC operation is +15%, -10%. Derate output current 10% for 50 Hz operation.

** DC Output:** See charts.

** Adjustment Range:** ±5% minimum except HAD Series.

** Line Regulation:** ±0.05% for a 10% change.

** Load Regulation:** ±0.05% for a 50% load change.

** Output Ripple:** 3 mV + 0.05% of output voltage peak to peak maximum. All 3-terminal regulator outputs: 3 mV + 0.2% peak to peak maximum.

** Transient Response:** 50 microseconds for 50% load change.

** Short Circuit and Overload Protection:** Automatic current limit/foldback.

** Overvoltage Protection:** Built-in on 5 V models, set at 6.2 V ±0.4 V. Other models use optional overvoltage protection.

** Remote Sensing:** On all models except HA and HTAA; open sense lead protection built-in.

** Stability:** ±0.05% for 24 hours after warm up.

** Temperature Rating:** 0°C to 50°C, full rated, derated linearly to 40% at 70°C.

** Temperature Coefficient:** ±0.01%/°C maximum.

** Efficiency:** 5 V units — 45%; 12 V and 15 V units — 55%; 20 V and 24 V units — 60%.

Optional OVP modules are available to protect your load from an overvoltage condition. These modules are adjustable from 6.2 V to 34 VDC and mount directly on your power supply chassis. The OVP-12 is available for outputs which will not exceed 12 amps and the OVP-24 is for loads up to 30 amps. One OVP module protects both outputs on the dual output ±12 VDC and the ±15 VDC power supplies. Note that models with factory built OVP are indicated in the table above.
