Performance comparison

Parameter	IS200EPSMG1A (dual-voltage)	IS200EPSMG1B (single-voltage)
Output Voltage	±15 V (dual)	+15 V
Output Current	1 A per polarity	1 A
Protections	Same + reverse voltage	OVP, SCP
Size	Same	10 × 8 × 3 cm

Summary:

IS200EPSMG1A offers dual ±15 V outputs and compact design. Compared to EPSMG1B (single voltage), this model provides both polarities with similar protection and efficiency.
