The Supereta™ Series offers an industry standard quarter brick high current power module with true useable output power. Its

90.5% full load efficiency (91% at 75% of full load) and superior thermal performance make the Supereta™ Series of power modules ideally suited for tight space and power-hungry applications in demanding thermal environments. This rugged building block is designed to serve as the core of your high reliability system. A wide output voltage trim range, -20 to +10%, and remote sensing are standard features enhancing versatility.

• Latched output over-voltage protection

• Auto-recovery full protections:

o Input under and over voltage o Output over-current o Output short circuit o Thermal limit

• EMI: CISPR 22 A or B with external filter

• US 6,618,274. Other patents pending

• ISO Certified manufacturing facilities

Optional Features:

• Negative remote on/off logic

• Short Thru-hole pins 2.79 mm (0.110”)

• Long Thru-hole pins 4.57 mm (0.180”)
